I'm going to attempt to write a little packetlogger in VB. This will only work for useast.battle.net:6112, however. My plan is to have two Winsocks -- The sckListen, which listens for a bot, and sckBNET, which connects to BNET when a bot connects.

When sckBNET recieves data, it is logged and sent to sckListen.
When sckListen recieves data, it is logged and sent to sckBNET.

When sckListen is connected to, sckBNET is connected to useast.battle.net:6112.
When sckBNET is connected, sckListen is accepted.

When sckBNET is closed, sckListen is closed.
When sckListen is closed, sckBNET is closed.

When sckBNET is connected to, the world is over.

That would work, right?

Just FYI, this would be more of a proxy than a packet logger; the way that actual packet loggers work is by installing a filter driver to intercept incoming/outgoing data through your network card(s).
