Mark Shuttleworth announces "the
Fan", a new mechanism for directing communications between containers.
"We recognised that container networking is unusual, and quite unlike
true software-defined networking, in that the number of containers you want
on each host is probably roughly the same. You want to run a couple hundred
containers on each VM. You also don’t (in the docker case) want to live
migrate them around, you just kill them and start them again
elsewhere. Essentially, what you need is an address multiplier – anywhere
you have one interface, it would be handy to have 250 of them
instead."

details on how it works.
