Anyway you look at it whoever pays the bills can do what they want. And chances are they will or are block many of the other file shairng programs too and not just gnutella. Whenever i see someone complaining about blocking its very common that they have tried 3-4 other programs too with no success.

If gnutella developers did do some measure to circumvent blocking all thats going to happen is that they are going to block gnutella differently like with things like packethound which was mentioned. It'd work for a while but wouldnt be a long term solution.

The disclaimer idea is something that indivdual programs would have to do most have ones kinda similar too it not that extreeme though. I've seen similar disclaimers like that on xxx sites.

This is probably a good reason why gnutella should try to be more than just file sharing which probably wont happen for a while.
