From the developer:
DeAvalon is an application restrictor that allows certain users to only have access to specific programs. Currently it removes non-admin access after a designated time though adds around 10 seconds (we hope this won't matter much in the long scheme of things).
You may want to check out more software for Mac, such as Gpg Tools, Tattletale or secureSWF, which might be related to DeAvalon.
