Assuming you have infinite bandwidth, that machine should be enough to
handle.. oh I don't know, nearly and infinite number of listeners.
You mention that you know "bandwidth is a limiting factor" but the fact is,
it is *the* limiting factor.
I bet you'll run into memory bandwidth issues (PC66/100/133, DDR, RDRAM,
whatever) well before the CPU of even a Pentium-133 would be taxed. I
probably manage about 2 minutes a day of CPU time with 10 listeners on an
athlon 1.2. By that yardstick, with 1440 minutes in a day, and each
listener requiring about 0.2 minutes, I should be able to serve 7200 users
from this single machine.
That is, of course, assuming I had a 675Mbit/sec line piped into the thing.
