Like splash says there are was around it.
Personally I don't bother even with the network mode. I run everything full screen and have keyboard shortcuts prgrammed in for messages, scenes I like. But then again I often only use it for a few hours at a time for shows, etc.
But further looking into multimon will be done. I want to look into it myself at some point. OPenGl can do I know.
But above all it is a visualization not a peice of VJ software. Visualization are designed to plugin in and play with no user interventation.
There are many things for REAL success and to be honest there are a couple of things above multimon IMHO.
