This does look awesome, though I think I'd need a lot of trust in it before I went down this route. It seems to take a pretty drastic approach and it's unclear how complex a schema it would be able to handle. e.g. how well would its use of triggers to synchronize fields work with a schema that itself uses triggers in various ways? I can imagine some weird interactions that could take place.

I'd also be a bit nervous that any of these tricks may themselves cause (perhaps temporary) performance problems.
