Lasers are clich`e. Tesla coil would get more immediate results.

We've opted to use Cisco's latest "Blue Laser of Punishment" technology to

after the first person is zapped, everyone else will get the point.
Blue lasers can be seen at around 1:35 into this high-quality documentary:

We used to put APs inside enclosures (ceiling or wall mounted), but when
upgrading to Aruba we decided to go out in the open not to deal with external
antennas. Moreover, the ceiling enclosures block some RF signal from bleeding
up, which is desirable in many locations.
We had one broken antenna in a Fraternity (billed to them), and we find
students messing with the antennas in the freshmen dorms (probably jump and hit
them). This changes the RF radiation pattern as we all know, so I usually send
a work-study to walk the hallways and make sure antennas are pointing straight
down. We have recently posted notes on each floor of the dorms letting
students know the entire floor will be charged if an AP is found broken. Maybe
this way they will police themselves. Or, maybe is just wishful thinking :)

Funny you mention that story. We purchased over a hundred AP-2000
access points from Proxim (was Lucent). These were 802.11b and used
PCMCIA cards as well. The idea was that we could simply upgrade the
cards when we wanted 802.11g. However, despite the original plan we
never upgraded those units and eventually replaced them with Cisco 1130
access points.
Cheers!

I remember one case of "vandalism". It was back in 2004 and we were
using Enterasys R2 units (They used PCMCIA cards), when the G
spectrum
was just becoming popular.
One enterprising student removed the Enterasys 802.11b card, and
replaced it with an 802.11g card. Unfortunately for the student,
that
didn't work exactly as he planned. The unit was still up, just not
working, took us a while to diagnose the problem. That wing of the
dorm had no wireless for almost a week.

Crew,
We hide our access points above ceiling grids. Our logic is the
devices are
out of site and less prone to vandalism (in fact we have had zero
vandalism).
One concern that has been expressed by our wireless team is the
congestion
above the ceiling grid – pipes, HVAC ducting, lighting and cables.
It is
logical that all of these obstructions do not help RF propagation
and create
sources of interference.
My question for you guys:
Did any of you change your mounting locations from above ceiling
grid to
below the grid (visible)?
Did you notice substantial signal improvement?
What is the vandalism rate?
Did your facilities/administrative folks express
any
concerns about the AP visibility?
