Hi, I like the idea of an indicator how generous/nice you are.... IF this is only an indicator without any restriction for downloading. Freeloaders are not evil, mode users are still not integrated and must not be punished.

I did call this generousity indicator "gnutella karma", which shows a ratio of how much you have downloaded and how much you have given back. Let's imagine there is a chat ability between future clients and you will see the generousity/karma (together with a title from 'A++ superpeer operator' to 'Big sharer' to 'whining milkdrinking freeloader') of your opponent... I guess such an indicator can encourage people to share and build a community.
