With icecast2, you'd probably hit network limits (with only 100 Mb/s)
well before you'd hit limits in the software or hardware. 

With icecast 1.3.x, scaling may not be quite as good, but should
be similar. I'd guess (but haven't tested) that you'd again hit
network limits first (or this MAX_CLIENTS thing, whatever that is).
