Interesting indeed - but I'm struggling to see who would want to buy a whitelabel IPTV service.
Sky: No way, they've got all the rights they need and are building their own network with easynet. They could add HC to it, but what would be the point? They don't have anything Sky doesn't already, or couldn't get with ease.
NTL:Telewest: Maybe, but only if it could extend their reach beyond existing cable areas. So "no" as HC is only operational in London, where they already have an infrastructure.
BT: No - their broadband infrastructure is massive, and BT Vision has all the rights HC has and more already in place for launch.
Rival Broadband Companies: Potentially, but they would presumably need their own investment in support staff, and marketing - a big outlay when your competitors are Sky, BT and the cable firms. They may just view it as a financial black hole.
