Than you for the suggestion. It is indeed an important issue. 
I confess that it is not easy to satisfy this requirement
in the current architecture: parsing fonts strongly requires 
random access to the font file, so the only alternative to file 
I/O is to load the whole font into memory. It is doable, 
but requires many changes in the code (and may entail 
a considerable memory penalty). In any case, we will 
keep it present when making plans for the future.

Best regards,
Nikolai Grigoriev
