DabbleDB is one of those products that I will probably never get to use despite being potentially very useful. Why? Because my company won't let me store proprietary information on somebody else's servers.
If you continue with this project, I would encourage you to consider letting people license the software to run on their company intranets. I know a lot of companies don't want to bother with installation support and such, but to me this seems like a pretty obvious market -- there are countless CRUD apps I could really use at work but just haven't had the time to build from scratch, and if DabbleDB had a not-outrageously-priced intranet solution, I'd buy it in a heartbeat.

Also, my first thought was that this was like DabbleDB. Is it?
