I don't know if this is possible or not, but I want to do a dual-boxing setup and ideally would like it to be across two machines. I have my WinXP desktop and a brand new MacBook Pro that I'd like to use. I'm not sure what software will work best for this. Multibox seems to be PC only so I'm not sure if there's another solution that works on OS X (I don't plan on sullying my MBP by installing Windows on it :P) and XP. Any recommendations or guides that address this particular setup?

Failing this, I guess I'll run two WoW clients on the same machine but I figured the two-machine setup is probably best.

Thanks
