I did sell streams for several years, and have to claim please do !NOT! use icecast. The "standard" streaming server is still shoutcast (sc_trans_040/sc_serv), even if this software is not maintained for nearly 10 years, since AOL bought Nullsoft.
Icecast extends the Shoutcast protocol at several places. This might be great news, if you have Icecast clients, but most of the shelf radios and tvs can only do ages old shoutcast.
An other warning: Do not use cloud providers like amazon, where traffic costs extra money, if you stream more then once. 1000 peak listeners calls to run your own cloud of cheap root servers and vps servers, and I also advise on GeoIP-DNS, with Nagios plugin to throttle servers that are already under load, and disable those who went down. You might do a lot of provider hopping in the early stage, so avoid long contracts. 500 average listeners is the legal distinction between a radio and an internet service for ASCAP, if you stream music. But 500 average is at least 10k in peak.
