Hi- We have a small securities trading company, and want to know if
there is a service available that will let us push regular TV channels
like CNBC, Bloomberg etc. over our 1 gig LAN.  We currently use
regular TVs but we'd rather not snake coax everywhere as we move to a
new office.  I was thinking by this time, perhaps there were some
vendors out there who are licensed aggregators of normal TV channels
for a situation like this.

Although I am not aware of any solutions that directly meet your
needs, I am sure they do exist, and I also promise that they would be
very expensive.
I reccomend you get a cable signal transmitter/receiver setup. This would enable
each T.V. to act as if it had it's own cable outlet attached to it.

Simply put one end where you DO have a cable outlet, and put the reciever
behind or close to the T.V. you DO NOT have a cable outlet at.

Here are some links to the items I am referring too :

The Videolan project www.videolan.org allows you to to do this with
it's software. Yould have to have a server that is connected to cable
to broadcast the signals to your clients via the vlc client software.
the software is free.
