I think protrusion might not be too difficult, but support for
expansion/shrinking of glyphs could be quite complex depending upon the
rendering API you have available. I can't really comment, not knowing
all that much about the internals of either. I have actually been
thinking some about developing a new outline font format that would
provide hooks for doing these and other things in a much more
programmatic fashion, but that is probably not going to happen until my
dissertation is complete.
The main reason I asked is I'm left with the dilemma of whether my
dissertation will look better using OpenType MinionPro Opticals
converted to Type 1 and rendered with pdfTeX and its microtypographic
support or whether it would look better using XeTeX without
microtypographic features, because I won't have to jump through hoops to
deal with the limitations of 255 glyphs per font, etc.

Sure, no problem. I think projects like the Linux port are probably
much more useful in the near term anyway. Thanks!
