I just skimmed over the intro; judging from that, I'd say it should 
indeed be compatible with POV-Ray's architecture (and licensing model), 
so it might be worthwile considering OSL support as a feature for POV-Ray 4.

Note however that OSL only addresses what POV-Ray puts into the 
material{} statement, so a separate language is still needed for object 
definition - and I'd advocate using OSL only as an alternative to some 
simpler material-definitions with roughly the feature(s), expressiveness 
and verbosity of POV-Ray 3.x's material{} statement.

Looks like OSL would be a kind of swiss army knife for material 
definitions - but when all you need is a decent pair of scissors, the 
swiss army knife's implementation of said tool would probably not be 
your first choice ;-)
