Ok. started implenting this and am pretty far in, but i have a problem
with uids in that dbus represents them internally as unsigned longs, and
if i expose these on dbus we'll have problems on mixed 32/64
archictectures. I'm pretty certain that uid_t should be a 32 bit entitiy
on both IAP32 and LP64, and if anyone knows this for certain i'll patch
it up. If not, i've just subscribed to so i'll just test
it myself. if uid_t is really 64 bits on LP64, i'll just cast up, but i
think this set of affairs would be pretty strange..
