Speaking from experience, it is totally possible to use a CATV
network as a MAN. Despite the low tolerances of your average 
CATV network, there is equipment available on the market that
can operate on a CATV system, as is.

We presently run a dual cable of  some 60 channels with
CATV, data, telephones and a hodgepodge of other
types through our network. This encompasses most of the Air Force
offices in the Pentagon-- Largest office space in the world.

We use Bridge equipment and have run the receive levels down into
the -30 dBmV range ( down in the noise ) without any detrimental
effects.
