Foo. coax is nice stuff. Cheap, installable by volunteers who
work for pizza, connectible without modification to every
piece of equipment under the sun, and best of all, multipurpose.
We ran 8 cables to each office node we created, and can now
use the extra cables to run anything we want (not just audio
and video) to each office (ie signals from motion detectors,
commands to motorized camera platforms, you name it)

we haven't had to use equalizers or clamps or any other 'voodoo' :)
... The only thing we had to be careful about was crossing
power lines at 90 degrees.

Our motto is to Do smart things with stupid technology. We've
remained conspicuously humble technically (except for some
truly groovy switch control software, borrowed from EuroPARC)
and have built a good network on the strength of our interface.
Doing it all with fibre optics would have been a real chore.
