okay. That's correct - am rather surprised to find recently that one cannot even
*view* the DSIG status of a font easily *on windows*; whereas I believe it is
easy/possible for executables. The DSIG status is simply not visible.

But I think signing is a good thing - not from the security point of view, but 
of
making font designers (or rather, font modifiers) less callous about doing 
ad hoc modification of fonts. I think requiring signing - or even just *showing*
the DSIG status - of fonts would improve the general quality of them.
