I've tested icecast-2.3.1 on a SGI box with a few clients, seems to work fine. I suggest keywording it ~mips.
Removing bug 245160 from Blockers as MIPS doesn't have any version of icecast.
Man, this bug is old. I'm going to close as WONTFIX since it's so old, but please reopen it if you still want this keyworded on mips. Thanks.
