In a "normal" sunray session, I can get the MAC address of the unit to

There is a way to get the ID of the current OVDC session using the
command line of the session itself?
You can use
dpy=`echo $DISPLAY |
sed -e 's/[^:]*:\([0-9]\)/\1/' -e 's/\([0-9]\)\..*$/\1/'`
ID=`/opt/SUNWut/bin/utwho -c | \
awk '$1 == dpy ".0" { print $5 }' dpy=$dpy`
That should work for both DTU and OVDC sessions.
The downside of this is that it issues a callback to the Sun Ray
authentication daemon, which may create a performance issue, if many
starting sessions do this at once.
A cheaper, but less supportable alternative would be based on
ID=`sed -n 's/^TERMINAL_ID=//p' /var/opt/SUNWut/dispinfo/$dpy`
Beware that the dispinfo files are not a supported interface, so this
may break in any update or even patch. But that isn't really different
from relying on the pathname underlying $UTDEVROOT.
