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.
