No. 64k sockets are all that is available on any box. W2k Pro will stagger
up to about 25k sockets, (providing that the load per socket is low, of
course:). Server versions may do better.

'Chat' is a TCP protocol, AFAIK.

IOCP and/or overlapped I/O is not trivial, surely, but is certainly possible
with Delphi. I have had the max. 24/25 k connections open with W2k Pro
without too much of a problem.
