That's already the case, for bzr, right?
Correct, in that there are native bzr branches on code.python.org, which I am currently trying to improve.
Furthermore, there is the option of hosting bzr branches on code.python.org, for committers, right? (not sure whether any committer makes active use of this service, though)
If we go this route though, then I think we should evaluate providing the same level of support for other DVCSs people want. I'm not volunteering to maintain the hg or git repos, but if volunteers came forward, we should reorganize the url space and authentication stuff so that they can easily be pulled from c.p.o.
Indeed. Before, I was worried about disk space. Now that we got a new machine, with plenty disk, RAM, CPU, we can offer hosting whatever people want to see - as you say, we would need a volunteer maintainer of such a service, though.
