You will need 2 copies of Keyclone. To be clear, you have to buy 2 licenses. Setup your PC 1 with the toons you want to load, then setup PC 2 with the toons you want to load there. Then get the IP address of your second machine (Start->Run->Cmd then type ipconfig). In the command line on PC 1 put in all of your toons and that IP address.

For example:

192.168.0.5;Michael;Jackie;Teeto;Jermayne;Marlan

Then when you connect it will connect to the Keyclone on PC 2. You have to manually start the other Keyclone on PC 2 I believe for those characters to load. This is how I do it. I have been 10 boxing for several months and I haven't researched a better way to do it because this works for me.
