I know that one can create & send a strange-msg packet (I tried, this
works). Such a packet that is semi-ignored by official client.
One could then add some TLVs with special T field (e.g. T=0xCAFE) to that
packet. I guess, these TLVs will be ignored by official clients.
And more: in these TLVs, one can embed one's own extensions of the protocol.
E.g. one can transmit a client version, or one can implement a "your party
is responding" feature (like one in MSN messenger & in IBM Sametime
I will not do this, but interested ones can try.
