Making subversion do things on commit is easy.  In the subversion 
repository's directory, look for a directory called hooks.  In there by 
default is a set of template files for each place in the process where you 
can do things.  For my own setup, I have a post-commit script that updates 
the appropriate website when a commit is done.  It's also handy with rails 
apps because you can have it restart dispatch processes or whatever else 
you need.  The script can be in whatever language is handy (bash, ruby, 
csh, elisp...)

I also used to do this with cvs using their log mechanism to call a script 
instead of a mailer, but subversion is much cleaner.
