AminetRadio has been looked at recently (especially in regard to squashing bugs and implenting a ShoutCast alternative), but the main problem holding things back is that MUI has diverged significantly. The intention is that it should always be an Amiga app that can run on MorphOS, but this is difficult if you have to support (and betatest) MUI 3.8, MUI 3.9, MUI 3.9 on OS4, MUI4 on MorphOS, MUI4 on OS4 and MUI 4 on 68k.

This is incredibly tedious to wade through and the author gelb just doesn't have the same time he used to.
