[Hosting] Fatalpha proposal

[Jon Carnes]

Mailman should move fine, though you wanted to move it to the new 
mailserver anyway.... Mailman works best if it uses a local mailserver and 
a local webserver, so where ever Mailman ends up it has to be on a server 
with apache running.  The only caveat with Mailman is that it might fill 
the logs after the move complaining about deprecated calls - since the 
Python verson will have been updated.  A re-compile would stop that (but 
blow away any special mods we've made).  Chris or I can take care of that 
in about an hour.

Quota's will need to be setup and maintained again - currently it is being 
done automagically via some cron scripts.

The SSH key for the server will change, so folks will need to delete the 
old one from their local key file (and automatically add the new one).

The Apache install of 7.2 defaults to Apache with Mod SSL so it would be 
cool to generate a self-signed cert and have https available.

Its going to be quite a task to get done quickly....
