I have 2 suggestions.
Suggestion 1: David robert Steele. I heard him recently on coast to coast:
it's paywalled, so I have the show on dropbox if anyone wants to listen to it:
he talks about his vision for the future, where everything is open-source. not just linux cd's, but our whole way of life. open hardware, software, servers, clouds, but also open communities, open government, and all other aspects of life. he thinks it's the only way that the 99% can liberate themselves & live in abundance. he also mentions interesting concepts like open-source intelligence, the idea that the people could collectively amass open knowledge equivalent to google, the NSA, or any other powerful entity out there. with this much knowledge, and ways of using it, we could compete with these gigangtic entities. and he also mentioned bitcoin a few times, and was in support of it.
I think it would be great to bring him on LTB, I think it would be educational & fascinating for all sides. he may not know about bitcoin 2.0, or the promise of spreading bitcoin to the other 6 billion, or many of the individual projects that are showing promise in the crypto space. medici, for example, is an open stock exchange, that will (hopefully) accomplish everything he's talking about. and it's real, it's being worked on. and while bitnation may be a bad implementation, the idea of p2p governance is real, and is being worked on.
so who knows, maybe he'll be willing to get on skype & give us an hour of his time.
