[LAU] audio and video straming

Hello, Does anyone have any pointers towards resources for streaming audio and video (it is intended for a conference type event, probably both for lectures and performances). I had some luck with ffmpeg/ffserver and I guess I could pursue this route but I wanted to see if there is anything else. I had a quick look at ices2 but did not see any obvious way to stream video with audio. I don't mind getting my hands dirty, worst case scenario I will write some scripts to allow those who will be in charge of streaming but I would rather find a good solution, alternative to ustream and other such services. Thank you in advance for any pointers. ./MiS
