If I understand your proposal correctly, it may actually be related to
the dynamic loading. Instead of just loading the ordinary compiled
checker, it might be possible to allow writing external checkers as some
set of rules or in some general-purpose scripting language. This might
make it possible to write simple, project-specific checkers.
But I'm even less sure here whether it would be possible, useful and
small enough project to do over the summer.
