I am not so sure -- printing pdf files with TTF fonts is not so stable
so one can drop the pfb's. At least printing to PS by AR didn't work for me
when I tested it.

I didn't try it yet, but I believe so --- especially  when you have the
.sfd files already.

yes that's right. We can take a look into that.
