Interesting. Are you allowed to distribute when "compressed" to
a more efficient format like CFF or OpenType though ??

The problem is that we need to support fonts that are not available
in PFB (and where the license prevents convertion), and the _many_
fonts that are encrypted.
There are maybe some ways to avoid "decompressing" the font in memory
by ckever use of filtered streams, but I haven't explored this issue.
Until then, using Postscript fonts is a memory footprint nightmare !!
