Yeah, I think a pseudo device might be a good way, it at least
makes the access permission matter of file properties :)

I wonder if this might not be handled partially via the envsys(4) API,
possibly when expanded a little to accomodate for additional
LongRun features. Or is LongRun something entirely different
and this would not make sense?
