Not as easy as that, unfortunately. There are two roof overhangs to
overcome, but the main objection is the cosmetic one of a cable running up
the front of the house; unlikely to be acceptable to my wife!

That won't work because of the capacitance problem. The sheer length of
cable in the telephone extensions - we have about seven - stops ADSL working
even when nothing is plugged into them. That's why I can't fileter at the
extension points. All the extensions are filtered just before the BT master
socket.

I might well have to try that. Sounds a good solution.
