I'm not aware of a pre-made system that meets those needs, but it's
fairly easy to make yourself. In my company we have written a
post-commit hook where developers receive diffs of commits to specific
directories -- the directories of the projects they're working on at
the time. Subscribing and unsubscribing is currently handled manually
through the system administrator, but it will be moved to a web front
end with a MySQL database in the future.

You do this by svnlooking at the revision that was just committed --
"svnlook changed $REPO -r $REV" will tell you what files were affected
by the commit. You can match these places against your list of
subscriptions and send out either the diffs or if you don't care about
that then just the names of the files that were changed about which
this person wanted to be informed.

You could do this by saving the youngest revision in a text file:
"svnlook youngest $REPO > /path/to/youngest.txt". In the cron task, you
would again get the youngest revision, and for each revision between
the previously checked one and this one, do what was described above,
probably summing up the changes for each user so just a single email
with all changes could be sent, rather than one email for each change.
Then at the end you write the youngest revision to the file again.
"svnlook changed" appears to accept only a single revision number, so
you may need to do a loop and call svnlook several times, one for each
