This is exactly what Demo module (http://drupal.org/project/demo) does.

1) Install the module.

2) Create a snapshot of your clean demo site.

3) Configure the reset interval and setup cron (see http://drupal.org/cron).

   - and/or -

   Enable the "Reset site" block, which allows users to reset the site manually.

4) Profit.

Demo module is also a great way to

- take arbitrary snapshots during site building and development (for testing potential modules to install, re-configuration, automated processes, data imports, safety backups before running update.php, etc) or

- test module update paths (from 6.x-1.x to 6.x-2.x) or

- even test entire upgrade paths (5.x to 6.x).

Rob Loach even went ahead and created a Demo installation profile (http://drupal.org/project/demo_profile), which may be an alternative to regular installation profiles in certain use-cases.
