Actually it is a dll called ByteCam and you can incorporate in mirc :) and u will be able to see users webcams, it works like a broadcaster, and there will be a list of active webcams. Google it!
try'd the bytecam :| the installer of the bytecam said: program to big to fit in memory, so couldn't instal it.
then installed MPP (mirc power pack which includes bytecam) it installed ok :| when i broadcast the cam (on private) and invite someone, no window appears (except the accept and close window). can only see me, but if i want to see myself i will go and look in the mirror instead (better framerate then) :)
so does it work? don't know. would it b a nice feature for mirc? yes.
u can even use it to "call" other people.
