1) Wireless LANS, at frequencies below 10GHz, are easy to monitor relatively
cheaply. (At the 10Ghz range, one has to intercept the path of the microwave
signal).
Commercial receivers are available that will happily monitor any frewuency
up to about 950 Mhz - If a TNC (with modem chip set for the correct baud rate)
is then connected in to a PC, packets received can be decoded and analysed
very easily.
An answer to this could be to use some form of publickey encryption. However
the basic problem with a wireless LAN is that it is essentially a 
broadcast medium, with the additional probelm that no physical connection to
the transmission link is needed.
An answer to this problem could be using Infra-Red laser transmission, if
your establishment has the necessary line-of-sight links. Since this
is of a much higher frequency, it will be harder to intercept (minimal
dispersion) and also your data rate will be much better (enough to run 
boot/swap over NFS :) ).
I would be interested to read followups on this topic - and also what the 
eventual solution to this project was.
