Hmmm... I like that idea, and assuming that it's fairly standard, I
would definitely be willing to change the way we do it.  In fact, I
intended to do some more research into how other distros are handling
it, but I wanted to get a working build out first and then handle the
tweaks and such later - I've just not had time to follow up on it.
If Debian uses 'plugdev' then that's certainly an option.  If anyone
uses some other distros and would like to chime in on this with
respect to what $DISTRO uses for that group, feel free. :-)

Okay, so if I'm understanding you correctly, to use those two as we've
currently got hal done, ivman would have to be in 'users' group and
pmount would have to be gid users, right?  If so, yeah, we need to put
some more thought into that...

Actually, let's hang on to them for the time being (unless there are
other problems besides the ones from above) and figure out what to do
with HAL first... :-)
