But it doesn't have to be a list of nodes; you could connect through an IP address of a friend, or one left on a forum, or however. And who says that there's just the one list of nodes? Several sites could offer up lists.

I'm not saying that you don't need a point of entry; clearly you do. But when any node in the network can be your gateway, I wouldn't class such a scheme as requiring a centralised server to operate.

Google Talk (Google chat?) uses an open standard, and I'd imagine if you took the time and effort layering a P2P transfer on top of the existing framework, something similar to Aol Instant Messengers (AIM) file swap.

The idea has been put forward before to use Jabber as a P2P network, though I don't believe any work has been done toward it. It seems to me that most P2P work seems to go into decentralised networks, nowadays.

In order to do what this guy is talking about, all the peers would have to have their ports open manually, or no router. Centralized wouldn't need this.

Not necessarily. Protocols like GNUtella and Skype use random intermediate hosts to bridge NATs. However, this obviously has the bottleneck of needing an third party to facilitate the transaction. I'll agree that a completely decentralised network isn't a good choice if you absolutely need reliability.

Considering you can create a p2p network where the centralized server only meets 2 peeps and nothing more, I don't see a reason to use no main server. All I can say is good luck.

I would suggest using an existing P2P protocol to save time, especially if you want to use a decentralised method. How about Gnutella?

No signle point of failure? :banana:
MUCH harder for anyone to close down.

Why would anyone close it down?

False.

Depends what its used for, if it has copyrighted music/software/movies i can think of a few people that might like to

I was just stateing that there's no single point of failure if its decentralized and harder for anyone to shut down.
