You could simply contact dcat with your request. He's normally available on the #Shareaza and #Shareaza-dev channels on P2PChat and he has probably also an account on the Shareaza forums (on SourceForge.net).

BTW, the graphics and data you will get from g2paranha are about the G2 network, not about the original gnutella. I think since the LimeWire team took off their gnutella crawler, there is none available for public anymore...
