The repository doesn't keep track of checkouts, so you cannot glean
that data from the repository. Ryan Schmidt has a script that can be
used to parse Apache logs to collect this information.

I would recommend against pulling this data from the log in realtime,
but instead populate a database with the relevant data (you'll have to
write something to do this for an initial population of the database
using a one-time output of svn log, then have a post-commit hook which
updates the database going forward), and generate your reports from
queries against that database. The only instance where this would
become a problem is if you regularly change revision properties, but
you can have a post-revprop-change hook to perform those updates if
needed.

Although I don't use it to retrieve/parse log entries, I use SVNKit to
interrogate my repository from within Java. http://svnkit.com/
