Interesting idea, but WHY?

You wan't to drop back five and punt?

1. Gnutella is an established protocol.
2. Look at the progress that has already been made in the development of the protocol and clients like Phex.
3. Gnutella has an installed userbase.

You might as well suggest that Microsoft and Apple both abandon their OSes and create a new one together that is incompatible with what everyone else is using. Would you buy it?
