On 06/26/2010 10:28 AM, arvid at cs.umu.se was caught red-handed while writing::
> There's a branch of libtorrent (http://libtorrent.org) which implements uTP and
> the bittorrent NAT holepunch extension.
>
> The holepunch extension is quite simple and relies on the two NATed peers to
> share one peer (which typically would have to be externally accessible) which
> will help them connect to each other by synchronizing connect attempts.

>> 2) mesh peers can transfer towards any peer which has a public ip
>> addresses (any host on the Internet)
>> 3) mesh peers can transfer towards mesh peers which are inside the
>> second mesh network

>> possible (which, as I said, are Linux box, or more precisely PlanetLab
>> boxes).
>>
>> Can you give some hints on what tecnique we can use, and which
>> bittorrent client. The clients will have to run in OpenWRT boxes, so
>> clients like Ctorrent, Rtorrent or transmissioncli would be fine.

>> Thanks a lot,

I also see the Encryption branch:
https://libtorrent.svn.sourceforge.net/svnroot/libtorrent/branches/encryption
which I am interested in.
How do I download the tarball for it, instead of file by file?
Or how about cvs or svn?
