I have been using livestream.com for the last two or three months and am extremely happy with it. I came across UPSTREAM which is basically the same as live stream.com. However, UPSTREAM as one feature that I really do like, it lets you disable the audio. As of yet, I haven't found a way of doing this within live stream, I suppose you could use WebCam without audio. Anyway, I've got it set up on another computer so you might like to check it out and see what you think. Let me know if you reckon it's better than Live Stream.
