(a little off topic) UTP by UTORRENT

“uTP measures the time a packet takes to get sent from peer A to peer
B, so in theory uTP will detect congestion anywhere on that path,
although in practice the congestion most often happens somewhere on
the first-mile uplink connection.”
So does this mean that the new uTorrent will result in slower download
times? Not necessarily. Since there is less congestion, uTorrent users
will experience no slowdowns in web-browsing, and ideally less
congestion and a more efficient use of the network may result in
faster download speeds. uTP is currently being tested in uTorrent v2.0
beta and thus far none of the testers have reported any significant
problems.

=======> I wait P4P instead of this ;)

the opportunity to implement it too."

The specs is closed...Let's wait and see how this new protocol works
well..

I read several articles about uTP in the past few days. The only
problem that uTP can solve I understand so far is just evade from P2P
throttling by ISPs. OK, it is a great improvement for some people.
I don't see any motivation to implement such low level TCP like
protocol stack to user application.
It seems LibTorrent-rasterbar dev guys have started to implement uTP.
Let's wait for BitTorrent.inc guys to publish the detailed study about
how efficient and effective uTP is compared to TCP.

Do they disconnect as you when upload/download peerrs are too low ?

BitTorrent protocol doesn't say client should disconnect slow peer.
Some clients may have the option to disconnect slow peer to prefer
faster one.

I think uTP is lower layer than BitTorrent protocol.
uTP itself is closed source, so we cannot know it dislike slow peers ;)
