I am using iswipe for powermac.
It shows that the gnutella(local) is showing zero files available.
It also shows gnutella(global) with 53.2 million files available, Hotline with 2.8 million, Carracho with 1.1 million and OpenNapster with 11.7 million files available.

This problem started two days ago. I thought it was because of an upgrade to 2.5.5, but that was not to be the case. Gnutella is not releasing any information regarding their local network being down. AudioGalaxy is up. Better to be patient, or for you mac users, you can get iswipe (beta version). It works alright, but you won't be able to see the gnutella (local) network, but you can still rip from the other networks.
