I'll save the story of how I ran across this, but I found it interesting. It's a seminar, held on M*U*S*H (an online massively multiplayer text based social environment), about ways to incorporate recent developments in RPG theory (scene framing, narrative control, etc) into online play, particularly in MUD/MUSH/M* environments.
Anything intelligent-sounding I'd have to say on the subject is pretty well covered in the seminar.
