For developers who wish to interpret 4-letter Gnutella codes as actual client names, here is some information for a client which will be released in 2003.

Code: SHNB
Name: Shinobu
URL: http://ashibaka.home.attbi.com/shinobu/

Good sleuthers will find all the info they might need at the URL.

I've added it to the peer codes on the GDF (http://groups.yahoo.com/group/the_gdf/)

If the client is (as your page says) for gnutella2, these is not the right place to add a vendor code or anything.

Mmm. Two conflicting ideas here: either "Gnutella2 messages will never be sent to Gnutella clients" or "Guruz ain't that bright". Seeing how Guruz is the gtk-gnutella webmaster, I would assume the latter proposition by Occam's Razor.
