As i understand RS is F2F type of software. Wiki says this:
A friend-to-friend (or F2F) computer network is a type of peer-to-peer network in which users only make direct connections with people they know.
1. Anonymous forums - this makes no sense. If we have to know people we communicate to then why would we want to be anonymous among our friends?
2. Anonymous file transfer - again this makes no sense since we know people we communicate to, whats the point to hide your ip from a friend? There probably could be cases where that is desired, but they would be rare ones. I have not seen anywhere an option that would enable direct (notice how 'direct' spells almost exactly as 'fast' except with 2 letters less and 4 letters different?) file transfers between person and friends / friend of friends / etc.
