A big part of it is development, but a larger part is a site
admininstration/management
issue: security, servicability, upgradability, backup.

As far as CVS goes, if we decide on a layout, the moving can happen at the
server level manually. Yes, this is more reason to use another SCM, but that
is another thread.
