You overlook a detail. You have to recompile or otherwise tweak your OS
to get 1000 clients. However, your plan is still valid for the real max
of somewhere below 256 (in most cases.)
However, I plan on letting one get full, and then check for other more
empty
ones. If I can find one, then the main server will close the accepting
socket,
and send a (proprietary) message to the more empty one. Then the more
empty
one (re)opens the listening port. Sounds pretty easy to implement,
relatively
divorced from low level OS stuff, and efficient.
