Most users won't reach that limit. Without further modifications, I'd
expect it to be in the hundreds. There is currently no known limit when
it comes to the number of listeners. Most installations run out of
bandwidth before they reach any significant system load - to spell it
out it's at least tens of thousands.
I know of instances that run up to 3000 streams in parallel, but I think
there the Icecast code had to be modified to achieve this.

Yes, we also officially support Opus (inside an Ogg container), Theora
and WebM, to name the most popular ones.
Known to work, but not officially supported are codecs like AAC and
h.264, but there we simply pass through the stream in "legacy mode" to
avoid any possible IPR issues.
