Ok, I agree on that, but in LinEx our biggest numbers are around 1000
workstation with 2000 users per network. They are still far away from
your calulations, and are working fine since september. And, obviously,
that's the worst case, most schools don't have more than 700 computers
and 1000 users.. , so , do you have networks with such size  (2000
machines & 50000 users)?,
If not, I don't see any reason to worry for a new setup different than
the current Debian aproach.

That's something I don't understand. Let's say user1 & user2 are in the
plugdev group, using different machines. If user1 insert a DVD or an USB
disk, he has full access to the DVD or disk, but user2 only have read
access to user1 hotplugged device. I don't see any problem with that
behaviour ...

But I don't see how user2 can access to remote device on workstation of
user1 with the current setup, unless it's shared using the network.
