Multibox Question/Thought

Has anyone with a hardware setup ever run Multibox with 2 clients and 2 servers running with 2 different computers handling each server?

What I'm thinking is upon death you simply hit your "switch focus to toon B" macro on the main, turn the key broadcasting off on the main computer, flip to the secondary computer (I use Multiplicity, so just a matter of dragging my mouse over...Synergy users have the same ability), and turn key broadcasting on on this secondary computer.

This would essentially allow you instant recovery and you would function EXACTLY like your main would (as far as I can see). I know the loss of my main effects my pretty hard as it stands, and I'd like to find the best way around this. Thoughts? Comments?
