I found the link by accident... and thought it's pretty interesting, also for advanced users. About Gnutella, the idea behind and the various undiscovered posibilities in future.
Hehe, also listen what Mark says about Limewire and Bearshare. Okay, every Programmer/CEO thinks his client is best... however it was very funny listening when he compares LW to BS!

I think we need more interviews from client developers. AFAIK there is only one one more with the XoloX guys on Zeropaid (in written form).
