cool, i'm glad it works.
just fyi -- you don't need 'stable' connections for the ethernet listings to work. due to some quirks in the way LimeWire handles connections, it won't let you search until you have an active connection. but technically, you don't need any connections at all -- the queries are sent directly to others on the network that have requested to listen for them.
i imagine you have the new limewire beta installed on the other computers in the network also?
