Ok, we've been experimenting with webcasting setups during the last couple of days, but there are several issues still left. The major issue is related to the audio source in Linux and how to control it -- only on-the-fly-encoding audio source providing tool we've found for Linux so far is LiveIce, but the problem is how to control its playback features remotely, using preferrably a HTTP link (that can be used via PHP or other scripting languages) to add and remove tracks to the currently active playlist on fly. For Windows, the setup is relatively easy -- to have WinAMP + OddCast + httpQ running, but Windows is not really an option in here. So, anyone, any help?
