Isn't mtxrun --script fonts reload enough ?

Only if you actually see the problem happening, which may not be the case. The output could be messed up without any kind of warning from the engine.

is there unique info in the font file that we can use? version number that is guaranteed unique? if so, we can pass that to the backend

There is nothing guaranteed, but fonts can have a UniqueID (inside ttfnames) that should be, if present, unique. -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer
