Oki, I've never looked at lxc, I was under the impression that docker
used to build on lxc in the past. Is that not true any longer?
Is there a template included for Arch? That would be quite nice
because building the docker image for Arch is a bit ugly I'd say....
Finally, what about running a 32bit container on a 64bit host? I've
not managed to find any indication that this is officially supported
in docker, but it seems to work just fine.

Well, I'm probably imprecise here. What I meant was that after the
service has been started (which requires root) any user in the docker
group can start images.
