Actually, I have once (must be about a year ago) started to implement this (as a excercise for search-query, and to perhaps use it). I never really used it though, and was not sure if REGEXP should indeed be a FieldCompareConstraint.
I could check-in my progress (still lingering here) and test it (in mysql and posgresql) a bit, to grant the wish.
It would be nice if there is a way to make a fallback for databases that don't fully implement regexp. I know that is probably quite difficult, not to mention performance intensive.
