If ssh is set up for rsync, it is simple enough to add commands to run
remotely in a script.

There are a lot of things called 'content management systems' that are
basically web sites with upload/management capability built in (joomla,
drupal, alfresco, etc.). They aren't likely to work unless you start
over from scratch with them for the web site design. If you already
have the sites in place you are probably better off setting up a
subversion repository and a staging site at the data center with the
servers (perhaps even running on one of them) and let the customers
commit the changes to the repository with subversion client tools and
work out a script that checks out a revision they specify into the
staging area, rsync's to the server locations, and ssh's the needed
commands. The operations should be relatively simple and as easy to
manage in shell scripts as some dedicated framework.
