Unfortunately, it aint gonna happen in existing LimeWire's.

An extract from our QueryReply code:

//Parse LimeWire's private area. Currently only a single byte
//whose LSB is 0x1 if we support chat, or 0x0 if we do.
//Shareaza also supports our chat, don't disclude them...
int privateLength=_payload.length-i;
if (privateLength>0 && (vendorT.equals("LIME") ||
vendorT.equals("RAZA"))) {
byte privateFlags = _payload[i];
supportsChatT = (privateFlags & CHAT_MASK) != 0;
}


That's probably the only area in the whole of LimeWire that looks at vendor codes. Oh well.
