Question on using 2 computers

[StephenMB]

here is my question:

I want both computers running 12 accounts each, raiding with all 24 at the same time, but using only one keyboard and one mouse the same as if all 24 were on the same box. So box one with the keyboard and mouse would control all windows, all keyboard pressed and all movements.

i hope that makes sense. Is that possible? I use inner space and isboxer. Guess I should ask their also.
