I have read a few posts about using Cat5 to send Sky and other services around the house.
Here is my set up and questions -
I have dedicated a room in the centre of the house (bungalow fortunately) to store my sky boxes x 2, Bose 321 media centre, wireless internet router,airport express and anything else that comes along.
I have living room and bedroom fitted with Cat5e cabling which all terminates in this central point but not used currently.
I want to have Sky piped to up to 6 rooms.
Sky+ to be in 3 rooms.
I have single coaxial cable to all rooms and only one cable in the main viewing room (doh!!)and cannot easily run additional coax from this room to distribute sky via loftbox. I can easily run many coax cables from the dish to the central "control room".

I can't get a scart cable from the main Plasma to the sky box its too far away so looking at the AV-LYNX system.
I think this will send sky and other AV to all rooms on command but is very expensive.
BUT if i want to use my Bose system i can get the base speaker into the room i need to using the existing cable but the speaker cables need to go to the plasma which is way further than the cable lengths which are supplied. Can these be extended or not? (i think not). It also needs to be connected to the Plasma. How? Will Lynx do that?
For regular music i can use my Airport express and Itunes via a laptop. Maybe i can work a better system for this using the Lynx system.
Ideally i just want to have all the boxes in one place and pipe AV to all rooms. Speakers for normal stereo can be fitted in ceilings (bungalow).
I know you need a converter kit for each room on the Lynx system which is what makes it so expensive.

Any of this make sense.
