Note that most networked applications don't send packets all the time. I don't for for certain if this is true or not for SL. What I have read about is only sending conglomerated packets of updates at a rate of about 10FPS. Clients (or in our case, the viewer,) interpolates motion between these 100ms average interval packets. The viewer at least does that... I've seen packets get lost, and my avvie just keep walking until it snaps back into position...
