Is it just me or is there a big movement to remove all the private network features from Gnutella clients?

I've spent hours in Google, installed around a dozen Gnutella clients but I just can't find a half decent one which supports a private network (specifying of a value for the handshake so only other people with that value can connect) and which support swarming.

If anyone could point me in the right direction I'd be most greatful, pulling my hair out here!
