A couple of more to add to the list:
retroDemiurgi - streams Amiga games all the way through (currently playing Enemy 2), plus AmigaLive, and other retro systems such as the NES.

Otter Retro - a unique EMU-VR experience, featuring plenty of Amiga games recently. Rather different presentation to most streams I have seen so well worth a watch.

Don't forget to check the first post in this thread for a complete list (or a complete list so far - there are bound to be more so do let me know if I've missed any. And of course - do follow all these good folk.)
