I love this idea, I don't really have a NEED for this idea, but I LOVE this idea. However a lot of us (including me) do not have access to MySQL, and I don't think that making UBB require more then it does in the original requirements list would be a good idea, nobody likes seeing something great that's free (as a hack would be) and not being able to use it because they didn't have the right stuff to run it.
