But have you seen how much Sky want!
Sky have two services, Sky Player for catch-up (aka Sky Anytime PC) and Sky Mutiroom (mostly a broadcast and catch-up service)
To watch Sky Multiroom on a PC or Xbox360, they want 10 quid a month ABOVE their normal subscription, and you have a limited number of devices you can use.
And Sky Player is a pay-per-view DRM'd system, which charges something like a quid-per-view (or in some cases, time limited download) or more for their most popular series, although some of the catch-up is offered free to Sky subscribers as long as you have already bought Sky Multiroom.
They are just complaining because Canvas likely to hurt their cash-cow, not because Canvas is not in the public interest.
The Sky HD box has EVERYTHING that is necessary to connect it to a home network and have a download service. Hard disk, OS, existing PVR software, Ethernet port, charging system, ISP for large parts of the country. But have they offered it to subscribers? No. They could have stolen a march over everybody but BT, and probably increased their customer base and had Sky HD adopted more quickly if they had, so if they are now complaining, it's their own fault for being tardy.
I'm now paying £40+ a month to Sky. If I put Multiroom and switch to their Broadband, it would go up to over £60 (non LLU area). I just feel uncomfortable putting all my eggs in one basket, especially when it is such a profit-motivated organization. Stuff that, bring on Canvas for competition.
Anyway, if it were not for the BEEB investing in some of these technologies, they would not happen. Freeview would have died a death TWICE if it had been left to commercial organizations (OnDigital and ITV Digital). And do you really think that Colour TV would have happened so quickly if the BBC had not been switched to it first. And I guess that you don't want FreeSat or FreeviewHD either, for the same reasons.
Anyway, I smell Troll, and it's not good.
