the CVS-version of Gem *should* support symbolic devices: so you could
send it a [device /dev/dv1394/0( message.
this is extremely untested, so it would be nice if you could give it a try.
(btw, if i remember correctly, it even attempts to figure out which
driver to use (but i may be wrong)
of course, exchanging the hardcoded device-name (as you proposed) is a
no-no.
