Heya Weierdguy,

I'm using Innerspace with ISBoxer to do what you are talking about.
Innerspace has a 10 day trial, but it does require a montly fee (like $10 for 3 months) but it is well worth it in my opinion.
The fee grants you access to all lavishsoft software.

And I highly recomend you use ISBoxer with it. It's a plugin for Innerspace that helps you set it up quickly to multi-box.
It comes with windowsnapper which will allow you to swap between screens very quickly and you'll also be able to broadcast keys (press "5" and the macro on your healer will heal your tank for example).

There's lots of general info on boxing in the forum, but check out the EQ2 boxing Wiki that we've been updating here too:

Good luck!
