The hosts of Free Talk Live know quite a lot about Bitcoin-- I had lunch with them last year (there's a thread in here somewhere about that....).
RE: "don't emphasize the potential illegal uses" -- mmmm. Last I heard, Ian was enthusiastic about the Silk Road, so I'd expect it to be part of the conversation.
And I think one of the people associated with the show (I'm being vague because I don't want to reveal something they don't want revealed) lost some bitcoins when MyBitcoin went away, so I'd expect security/trust issues to be raised, too.
