Whilst I'm prepared to consider moving to git we need to give serious 
consideration to whether we want to host on an external site, if only 
from the point of view of maintaining a solid set of backups.

I don't have that as such, but if you can give me a list of usernames I 
should be able to come up with a list of addresses.

Well apparently we can setup our own github if we want, but I will need 
to look at that.

What is deploy.openstreetmap.org exactly? In order to make deployment 
work we need somewhere we can pull from to multiple machines.

That presumes that aliens-ate-github.org has somehow magically gained a 
copy of the code from github before the aliens arrived.
