Now how on earth did you know I was thinking about this Island Dog?  Now that I have two computer with their own monitors sitting either side of a 37in LCD TV this sounds like what I need.

So this takes the place of a KVM switch, I am right about that?

I guess I need to click on the link and learn more.

EDIT:  Okay, need someone to explain '.... and a TCP/IP network between machines is required.', just what are we talking about here? 

As long as both machines are on the same network, you're covered TCP/IP wise.

And KVM wise, there is no "switch" aspect.  As your mouse cursor moves to the edge of one screen, control is handed over to the next screen.  It's as seamless as just sliding the mouse from one monitor to another.  The keyboard commands are tied to wherever the mouse is. 

I swear by Multiplicity Pro. 

What's the compatibility like between crossing OS'es such as from Mac, Linux, and Windows?

Keep climbling CAD$ (0.8577 now!), soon enough i'll need this app possibly more than any other games!

Besides, there's some very important stuff on the XP system wired to an off-switched CRT which i've been staring at for months. Makes a few USB sticks worthless and yet, i've got drawers of Floppies & CDs that could use efficient mobility in a truer sense of the word.

Being able to copy and paste files (using MP Pro) changes everything.  So very awesome.

There is an open source program that does exactly the same thing:

http://synergy2.sourceforge.net/

Get it instead and use the money you would have spent on multiplicity to buy a copy of demigod for a friend

Very cool. Now all we need is a way to boot both OS's in dual boot, display each with a twin monitor setup and control both with MP.

(drools at the thought.... )

Actually, I used to use synergy. but now I don't...here's why...

Pros

1)  Free

2)  Works with OS X, etc.

Cons

1)  It hasn't had any updates in three years.  It's abandonware and there's no sign of any of its bugs ever being fixed.

2)  It doesn't support copy and paste like Multiplicity Pro.

I used to swear by Synergy and now I swear by Multiplicity Pro. 

How many times have you MP users set your laptop down next to a friend or family member's PC and then banged your cursor against teh side of the screen (multiple times) expecting it to just work?  I've done it more times than I am able to keep track of!

Hehe yes, been there, done that. OFTEN.

I use and reccomend Multiplicity to people regularly...

Now, if only Stardock would make a new, better, version of Ultramon!!!

Ohhhh, that would be cool.

I have MP on 3 computers here; 1.Vista/Win7[dual boot], 2. XP pro, and 3. XP; plus I have a Linux laptop which I prefer to leave as it is. So as I do have an extra keyboard via laptop... to use without changing other things I'm doing for Windows. Kind of like it that way in case windows throws me a punch. I just punch the Linux and get answers or whatever I need. The Linux is setup for my file shares also and has access to my Home Server to boot... this makes it even better so if I need to pull in something to do a little bit of research or just look it over.

Had Win7 crash last night due to a disk error caused by MFT failure. Was to small and system files where lost. Thus reinstalled after a better setup for MFT sizing and all is good to go now. Funny how windows does not see NTFS as it should. And once a MFT fails there is no fix via windows restore or even repair via Win7 files on DVD. It is time to say good bye and reinstall again.

Multiplicity helps me test all kinds of software. Plus that of VMware to keep things good to go with most stuff. But even with that the ole fashion install tells all the tales.

But without Multiplicity I'd be in trouble having to figure which keyboard and mouse is what. Plus having a place to put all that junk. This way I have my wireless mouse and keyboard for all of everything.

I actually use one system for testing and another for monitoring the test. Then the other to get info or just work my mail and IRC with other messengers to keep in touch. But it is like one is google, another is MSN and the other a clean system with no mails and/or any other type of office stuff. Just ready for test with a VMware partitions. Really do not care much for OS in virtual system. Not when I have MP to use and do things cleaner and up front. Thus I'd be wating on OS partitions and watching too much also. Try to keep it simple with MP and a fair setup. MP helps a bunch.

Can't live without it  - NO WAY ! One hell of a good program. [ Just watch them there secure windows - will mess with you - but what else is new ... anything secure like UAC and such does about the same no matter. ]

If your gona buy - Get The Pro Version !

There's also a free and open source alternative called synergy.  I think the one thing multiplicy has over synergy is the ability to copy files

Here's a link to synergy

http://synergy2.sourceforge.net/

Here's a post comparing their differences

http://www.donationcoder.com/Forums/bb/index.php?topic=2447.0

Synergy only supports copy and paste for TEXT, like urls, etc.

Multiplicity Pro supports copy and paste for text and FILES...a tremendous difference.

Note that when I run OS X machines, I run Synergy AND Multiplicity on my Primary computer, Synergy on the Mac and Multiplicity on the other Windows PCs, of all flavors.  So these two programs do work together if you need them too. 

Another bonus for both of them.
