Communication between clients isn't done using FLAPs/SNACs, that part
of icq is still very similar to the old protocol. The handshake is
almost exactly the same, except there is an extra byte on the start of
packets and there is an extra exchange (so there are 3 exchanges). I
don't have anything solid written down, but you're welcome to take a
look at the sources for libicq2000 (it's in DirectClient.cpp you want
to look). It's also almost the same pathetic (and broken) 'encryption'
that is applied.
