Non gnutella/limewire Hosts?

[Maxim]

I'm connected just fine using the default hosts ... however, I have a concern, which is that obviously, I'm connecting to the cetral server provided by the nice Guntella/Gnotella/etc folks (I'm using Gnotella) .... If (when) the lawyers get around to messing with gnutella, I think the central server will probably vanish, while gnutella peers live on and try to share with each other ... My question is if and when this happens, how do i continue to share files?

The obvious answer is that I connect to others I have connected with in the past, and bypass the gnutellahosts.com and router.limewire.com hosts altogether. The question is, though, how smart is my client? Does it have a large cache of all hosts I have connected to? If so, I can't find it. Do I have to just pay attention and go through the tedious process of adding hosts i see connections to/from to my pulldown list? Does this vary from client to client (probably so)? If so, what clients are best for recording and retaining hosts that I have connected to for future use?
