I play 2 accounts of eq2 on a vista 32 and vista 64 with multiplicity. Works great in the way it is supposed to, but not in the way I hoped it would. Let me clarify.
PRO -All features stated work like they should, it moves smoothly from one to another, is essentially transparent and I love it.
CON -I have a G15 keyboard. Basically, among other things, its got this massive bank of keys which you can set to be a macro. In theory you would have a setup like:
comp1 - tank character, main control
comp2 - healer, character 1 targeted, on auto follow, heal spell hotkey is #1
Now, you want to be able to control character 1 but be able to cast a heal spell without switching, just hit a keyboard button. So, you set a macro on the g15 keyboard to do the following:
1. press and release multiplicity hotkeys for monitor switch to comp 2
2. press the #1 button and release
3. press and release multiplicity hotkeys for monitor switch to comp 1
The problem is, switching takes quite a while (from a macros view), and the time is extreamly variable. I havent been able to put enough pauses in place to ensure that it works consistently without having to wait 3 seconds or so for it to be done. A problem if you want your off character to also nuke, and they have a few heals, etc etc.
What I guess I wish it would do is be able to cause a non "hot" computer to get the signal to press/release the #1 key without having to switch. Basically push the control to the other comp. To my knowledge there isnt a way to do this yet, so controlling two characters is rather difficult and you get very little added from the second.
All in all a fantastic prog that I am incredably happy with and suggest to others, just doesnt quite hit the mark for my 2boxing desires. (not to mention 6 boxing)
