[Babel-users] [homenet] sorting out the right ipv6 addr to choose and name in a source specific world

I'd like to attract your attention to the work that Matthieu Boutier has
been doing on mosh, Keith Winstein's UDP-based ssh replacement:

  http://comments.gmane.org/gmane.network.mosh.devel/749

Boutier's version of mosh builds connections across all source/destination
pairs, and picks the one with lowest RTT.  It's a work in progress --
there are multiple versions, and Matthieu has yet to decide which
implementation he's going to submit for inclusion in mainline mosh.

We hope to write that stuff down when Matthieu has decided which is the
"right" version, but I'm not promising any hard deadlines -- we have a lot
of stuff that we want to write down.

Uh-huh.  But there's only one thing that's worse than generalising from
one example -- it's generalising from zero eexamples.

I'll have a look, thanks for the pointer.
