[Icecast] General Server Hardware Question

Hey List,

How do people measure how many listeners they can have on a single NIC
card? A 1Gig Ethernet NIC card maybe able in terms of bandwidth to
serve 31,250 listeners at 32Kbps (not including overheads etc, just a
flat calculation) but there is no way the NIC card its self could
handle 31k concurrent connections to 31k different IPs on 31K ports?
(Obviously the OS comes into play here a bit also, but forget that for
a moment I am just focussing on the NIC card its self at the minute).

So how do people calculate how many servers or NIC cards per server
they will need to handle this many connections?

(Ok, 31k is a lot but even 100 or 1000, how do people calculate this?)
