D2 multiboxing?

Anyone know of software that could possibly help multibox d2? D3 will eventually get old very soon, I am just finishing up being bored solo playing so my next adventure will be multiboxing, but I know that won't last very long.

D2 is superior in every way, it would be awesome to box 8 chars in that game. All I really need is a mouse and keyboard broadcaster, no fancy macroing, round robining, or video streaming.

I'm not sure how it would launch multiple instances, D2 is unique in that each instance launched must be tied to a different CDkey, and you need to "hack" the game by replacing a DLL to let it launch multiple times.
