No exchange. hal-info just installs files into /usr/share/hal/fdi/foo -
or do you mean the hal specification interface? I hope the hal spec will
not change, and if it does, we'll need to provide fallbacks so any
version of hal-info can be used with any version of hal.

That would be an ideal situation IMO. Updating hal-info should break
nothing, and make more stuff just work.
