Kyanar:
It's got an eSATA port. They COULD just enable that? (And to be honest, they likely will since Tivo will undoubtably have their external HDD addon)
I'd say the changes of Sky enabling the eSATA port and allowing any non DRM certified device are about as high as Sky giving everybody free service for a year..
You do realise the Tivo is probably one of the most DRM ridden devices on the market?
