i tried this--no dice. but i'm starting to think that this
is specifically a nautilus problem. just doing 

su - ryan -c "$PROGRAM --display=:0.0"

in the hotplug script (without setting XAUTHORITY) works for 
about everything i've tried, including gnome apps, but not 
for nautilus. unfortunately, nautilus is not printing anything 
to stdout or stderr, so i can't figure out what it is missing, 
and no one on the nautilus-dev list seems to know either.

anyway, thanks for the suggestions. i'm interested to see
what comes out of the discussion i unintentionally sparked.
