I ~might~ be able to do it. I've been looking for some way to help out for a long time, but my lack of programming skills sort of limits my options.

It would be impractical for me to look for all the features myself. If I do this, how hard would it be for me to get developers to submit a list of their client’s features? One problem we may have is that gnutella is developing very rapidly and things change so fast. By the time we get the first list out it may already be out of date.

I think this is really needed because it is hard to tell which clients have what features. I don't even know exactly what features some of the clients I use have.
