I doubt it.  First, the units are all single-drive SEs with a hard
drive.  In general, students bring their data disks, and then just
sit and work with MacWrite or Microsoft Word or whatever (all
available on the hard drive) on their data disks.  I've noticed
that those who do bring their own APPLs in general install them
on the hard drive while they're working, then delete them later.
Second, they *already* have to queue up at the front of the lab
to get their disks checked by the operator at the "disk-check" station.
This process has not decreased lab traffic noticeably.  I doubt
on-line checking would do so.

What I was thinking was more along the lines of an INIT which simply
passed control to the checker.  Then the checker checks *the internal
drive* with no need for documents or such.  Is there any way to
do this?  Or do I *have* to have a "pathname"?  I've only seen
one problem so far: what to do if a disk is inserted while within
another application.  So how about a check in the INIT -- do this
only if in Finder (can you check that somehow? or maybe link the
thing into Finder itself?)  Something like this would protect
the heavily-used Printer Machines (one per laserwriter, used
only for printing) *much* better than the disk-check station.  And
the other machines would benefit as well.

Unfortunately, I ain't got the time or expertise to do this.  I'm
just learning about programming on the Mac.  And whew!  What a machine!
It'll take me a few years before I'm ready to fiddle with my
Mac's insides via INITs.  And hence the "call".
