Hi Torben, Allows me to offer my 2 pences.

So if the delta has been submitted to the server successfully, then your client should receive an acknowledgement doesn't it? And each instance of your client has unique port/IP address pair so there shouldn't be confusion on who has sent which delta, as each delta is sent over independent and unique connection to the server. If one delta from client 1 has been received and not the other from client 2, then client 2 should operate with the assumption that it should send the delta again doesn't it? Hence I don't believe client ID is necessary when submitting delta as TCP should have been sufficient. Or am I missing something here? cheers, Chiang
