I looked into this before and, if I remember the figures right, to view from Sky's site with subscription is around £30/month whereas via Iphone app or Vodafone movile TV it's about £6/month. So aswell as a technical issue with Silverlight that would stop us streaming it on the n900, it's also quite a bit more expensive. Relying on JustinTV is a world of frustration usually. I think I did notice something about Sopcast appear in a thread recently, though data usage would sky rocket I'd imagine.
