The impression I got from talking to the BBC when Jimbo and I were there last month, and from the meeting I had with iCan this week, was that they are intending to release some of their content under a free CC licence, rather than one of the more restrictive non-commerical ones. They have also shown an interest in using Wikipedia content under the GFDL, although this isn't going to happen immediately since such things need to be checked with their lawyers first.
