Three rewrites and not yet out of (or even in) beta: http://nuuton.com/

If you are seriously hoping for this to be a full time business then I would strongly recommend you read "The Lean Startup" or similar. This blind technical pursuit of perfection is a pretty classic approach for us techies and something i'm guilty of myself. It was actually that process that made me realise what my strengths actually were and what I would need to do to start a world class company (work with great people).

If this isn't really a commercial project then just ignore the above and happy hacking, perhaps you should consider open sourcing it?
