but a bit of technical details as you all love them :
as copy/pasted from the wiki :
http://giss.tv/wiki/index.php/G.I.S.S._Icecast,
a release of an Icecast special version for G.I.S.S. has been made this month,
some modifications might be useful to some other projects
and fixed bugs has been imported in Karl Heye’s branched icecast.
The G.I.S.S. icecast is only fit to run on a master server and needs to
be connected to a G.I.S.S. server database, so the slaves should run an
icecast >= 2.3.2-kh5 from http://www.icecast.pwp.blueyonder.co.uk/
