If the node want to join the gnutella network ,it is the process called bootstrap,so where can I gain the initial nodes list to connect.

I see it from the limewire wiki,it is called the GwebCache,so if I just to make my client to work with standard gnutella network,so do I need to do the same thing as the limewire client or something else?

Is there any simple research gnutella client to make me understand more easily? I am a newer want to write a gnutella client from scratch.

Thanks!
