I don't know when I'll do another live performance. They really stress me out, which is saying something for playing ambient music.
The web video thing was a fun thing to try, but it really pushed the limits of my system since I already use it to produce the music and stream it to the server. I was surprised that the system held up as long as it did, and I only started getting some intermittent snapping after 50 minutes or so.
That said, if I do another live show, I'll likely lug in another system into the room and use it solely for video streaming to the server.
