RE: [core-dev] Re: [codepatch] Bittorrent v4

Well, as long as we don't break the BT protocol and clients.

Note that we also want to shy away from sending UDP messages unless we know
that the person will accept those messages.  I think it is bad form
otherwise and potentially damaging.

Thanks

Shareaza did not extend the protocol. On the contrary, Shareaza was (and may
still be) incapable of accepting incoming BT connection. In addition their
choking/unchoking mechanism did not work as specified by the protocol.

With regard to the extensions I had in mind, other Bittorrent clients should
stay completely unaffected by them. I wanted to exchange something similar
to
the new head pong messages carrying information about alternate locations
and
eventually some information about the SHA1/TigerTree root hash of a file, so
you
  can try to download the file via Gnutella if the tracker fails.

I find that BT trackers are failing quite frequently, in one out of ten
attempted downloads the tracker will not respond (independent of which BT
client
I use). I think that this will cause some serious problems in the not so
distant
future. I'm also going to implement the UDP tracker protocol soon, but that
is
obviously not really popular yet and Bram Cohen's reference implementation
doesn't seem to support it either.
