its a screen shot of some random bit of code, i think he's trying to show the class name of CWPNPrimary to show it has a primary connection for listing... but i think anyone would have made that assumption anyway...
Only thing it really shows is he has a lot of classes, so it doesn't look like its going to be very efficient... more than likely still use less resources than winmx does though, winmx is a real resource hog...
I also noted from his locking and unlocking that he's obviously using multiple threads for at least the listings part, and my guess is he'll do that for the chat clients as well (although without seeing the source... anything could be going on) - if he does use a thread per client, i hope he does it in a more stable way than i managed it, 99% of the crashes in MCS where caused by threads
cant really tell much more than that from what he's shown/said... we'll have to wait for release..
(and btw, this is one of his programs i actually will be waiting for... lol)
