The font format used by all "smart font" technologies (OT, AAT,
Graphite) are all based on the TrueType font file format which allows
you to add any number of custom tables. If the people responsible for
the OT, AAT & Graphite specs agreed on it amongst themselves, it might
be possible to specify an embedded table of properties for PUA
characters that all the different rendering engines could read and
make use of.

That might not be completely "font-technology independent" - but pretty close.
