Linden Labs has filed their paperwork in their court case which has the potential to be a landmark in the virtual world domain. Matt’s got a good writeup, as does Prokofy Neva. I heartily recommend taking the time to read the writeups, and contribute discussion on Matt’s blog whose following details of the case much closer than I am, but I think the whole case has deep ramifications for anyone trying to protect their environment from troublesome elements.
