[pygame] Re: a gsoc idea: networking


That sounds remarkably like Bittorrent. If you check the internet
archive or other sites, you should be able to find the Python code for
Bittorrent before it was closed.

About server discovery, my concern is that most systems can be easily
polluted with malicious entries. Look at all the issues with DNS
(which is pretty much exactly what you propose), and what needs to be
done to prevent ARP poisoning attacks. Any such system would have to
be designed  to distribute the authentication in a secure way. And if
attackers have control over one or more nodes, it can be difficult to
ensure authority and correctness without a centralized server, hence
the Root DNS nodes.

It sounds like some interesting ideas, but the problems are ones that
still stump PhD's...
