Well, I did put in a plug for Home Education to Mark Thompson, DG of the Beeb. We both agreed that the future lies in personalised learning, and that the BBC could be hugely helpful in this regard.
I then explained that HEors find completing the coursework component of public exams problematic and often expensive, and if he could see his way to thinking about this issue, we would be very grateful. Naturally enough, he was then interested to know about numbers. I admitted that we don't know at present, but that HE appears to be a growth industry.
He also told me that BBC Jam is now fully operational, as of last week, so am off to check it out.
