     Well, when I ran my public proxy, I did get quite a few hits
from people on corporate networks. Most of the people who
connected through my proxy were listening to Internet radio.
      A lot of admins were obviously clueless that somoene could
connect to my public proxy. There are quite a few clueless
admins in the IT field.

       That is a prohibition that does not make sense. There might
be a piece of software that someone may need to use, that is
not available on the company network. How are they going to
know anyway? Your login and password are going to be the
same no matter what computer you use to connect to the
corporate network.
       Where I went to college, faculy and staff often brought
their own computers and plugged them in, in their offices
and nothing ever came of it. One professor even had three
computer once, his laptop, plus two others, that were plugged
into the network, by using a splittter, to plug three computers
into one network outlet, and nothing ever happened to him.
How would they have known anyway that he was plugging
three computers into one network outlet in his office?
