Yeah, sound like a reasonable thing to do. However I'm not sure how much our av is loading the CPU side when they are stationary (physics should be in "rest" mode), would need to investigate a bit. For us at Meshmoon I need to optimize many things in the js script side before doing things like this, although this is a easy thing to add quickly. Mainly I'd need to implement the few optimizations from the Tundra example avatar scripts. Using only one script engine and using the EC_PhysicsMotor to drive the movement on the c++ side. But our av script has lots of other optimization the core example does not have, we have been running 30-40 avatars with our script without server breaking a sweat.
Would be fun to get to 200 avatars with Tundra before OpenSim :) Of course it might be hard to compare the things you can do with your avatar, smoothness of movement etc. but still. OpenSim has quite the leg up on the optimization work, I think they've been doing it for years now (I remember in ~Naali times when they wanted 100 avatars and were working actively on that goal with Intel if i remember right).
