I've got direct connections working in my client ickle. They are very
similar to icqv5 connections, except an extra stage of
handshaking. Turns out the encryption is the same as v5 too except
there's a byte (0x02) inserted at the start of message packets. I
don't have anything very neat written down, you'd best look at the
libicq2000's sourcecode (http://libicq2000.sourceforge.net/).
