With Icecast the basic rule is:
- you run out of bandwidth before anything else

The rest is fairly simple bandwidth math.
Just keep in mind:
128kbit/s = 16kbytes/s
Also take into account TCP/IP/Ethernet overhead. I don't have a hard
number at hand, but I'd just multiply stream bandwidth by 1.1 or 1.2.

I'm a bit surprised at the low monthly data volume of 6GB you state, as
that is unusually low for a hosting arrangement nowadays and translates
to 5500 broadcasting minutes (about 0.13 average listeners 24/7/30).

Or did you mean something else than hosting an Icecast server?

Cheers

Thomas
