It's not perfect, because (if you know what you're doing) fonts can be installed in Mac OS X from other places and fonts can also be disabled but not removed from those locations, but it's the best we can do at this stage I think.

An alternative is to write a binary lua module that interfaces with
system API's (it can be even abstract both Apple and FC API, and
whatever MS provides), but someone have to write it first :)
