Would it be an issue if I were to run two applications off of one database?

One application is a phpBB, and the other would be for tracking that site. Size will not be an issue (my hosting company offers 100MB for each server, the BB is using up less than 1MB right now and I don't expect it to explode).

The other application would be a site-tracking application, like AwStats (if they require a db).

I have plenty of databases available, but I want to avoid any future potential cutbacks.

Thank you!
