I didn't realise, until reading this thread, that Adam was Joe Henson's son. Never met Adam, but I was privileged to work on some of the programmes that featured his dad, way back in the early 1980s.
Mr. Henson senior I remember as a quiet, patient and charming man. TV production of that sort is invariably a lot of hanging around waiting for other people to do their stuff, and thus stressful and tedious - frustrating if you're waiting around, and stressful if it's you holding everything up! Joe Henson was one of those contributors that made the job enjoyable, not just for the content, but the people one worked alongside.
If Adam's a chip off the old block, I hope he does very well.
If you want to go after BBC commercial tie-ups, start with Radio One. It's always had a reputation for big money splashing around (from the music business). I doubt that's changed. And those 'privileged' to live close enough to Worthy Farm, but outside the Area of Patronage, still have sleep interrupted by throbbing bass, crops damaged by convoys of hippies, clagged-up roads, "petty" crime such as house break-ins, and lots more 'benefits'.
Last year (2012) the BBC sent around 300 people (274 technicians plus artists). I wonder how much they pay the Eavis empire for that, never mind the fees to the artists. Yet, if they didn't plug it so extensively (every station, for months before the event), I wonder if it would be a sell-out every year.
In that context, Adam Henson's farm is nothing. And I have no doubt which one is better for the environment, too.
