So... hardware multiboxing?

[nodoze]

you could. But if you're going for a round robin type setup, I don't think you need any sort of virtualization at all (no need for aster). You can macro some "alt-esc" keybinds into your normal rotation.

Good Call, Seems to be working well so far, just need a to tweak a few of my macros and change a few keybinds and i should be running again
Ill have to get my stream set up set up again lol.

My main problem with the Alt-Esc approach is that it is relative to the last window you were on and only goes to the next window. That works pretty well for the DPS but doesn't really help for the Tank/Healer as much.

You may actually have a better result from incorporating both approaches... For example for Tank+Healer+3DPS:

You could do Tank & Healer on your primary desktop where you drive from the Tank and mainly use the mouse to heal from the healer like 'Tuts does here'

Then via hardware (KM synchronizer) send round robin keybinds with alt-esc to the 3DPS which could be together on a single PC/VM/Virtual-Desktop.

At most it would be a 2 PC setup but could easily be a single PC setup (via PC+VM or regular desktop+virtual desktop).
