[Icecast-dev] iPhone patches question

[Bob MacCallum]

Thanks all.  I've been looking at the Tuner (by Nullriver) app as a
hypothetical solution (since I have no iPhone).  I'll point my users
to WunderRadio too, in case they already have it.  If Tuner2 handles
.pls playlists (a necessity for me because my icecast server is on a
dynamic IP) then I'll recommend that too (when it's available).

I've heard that apps don't background.   So when you switch from the
radio app to another app, the music will stop.  Is that correct?
Switching from audio stream player to web browser is critical for my
application (interactive evolutionary music at
http://evolectronica.com).  I imagine it would be really nice to
evolve tunes when out and about!

A dedicated free app for Evolectronica would be really nice, but I
don't have the time for it, or enough love for Apple...

thanks again,
Bob.
