Two quick links that seemed of potential interest:

Game Politics reports on a call for an “avatar’s bill of rights” that would recognize virtual representations of people as governed by rights, not just end user license agreements (presumably only covering those in online worlds, but I haven’t read the whole article it links to yet).

And on a related note, GameDaily reports on the virtual “death” that may ensue from the nigh-inevitable government taxation of virtual goods and services.
