The author of this thread brings up a VERY important point.

Do not underestimate any of the forces who would stop file sharing, and be ever vigilant for attacks on the network - they take many shapes and forms.

I would like to also point out another scenario - they could simply offer an existing Gnutella servent (BearShare?) a lot of cash to take over their product in secret.

They would have to pry BearShare out of my dead fingers before I let that happen.
