C5's catch-up service is an imminent addition to Bravia Internet Video and I know that talks for iPlayer, ITV Player and C4 are at advanced stages.
There is also a FiFA BIV service going live (which will run to the end of this year) and content from the Berlin Philarmonic.
I will shortly be leaving the Sony fold (more about that another time) so won't have access to this information in the future.
Agree with matengawhat BTW.
