Wouldn't see why not, there would need to be a buffer holding data untill a 
free clock cycle appeared.....

Not as far as i am aware, i know ADSL is controled at the exchange, so you 
might need to have a mighty ££££££ bit of kit to do it. You would be better 
off getting those wireless networking kits that run through the mains....
