I'd like to have a serie who would be interviews of Asian experts, especially University Teacher in "Asian studies" department. Those interviews could cover many subjects, like economy, politics, philosophy, litterature, religion, arts, and so on.
1 episode/1 interview a month like that would be really great. It would be "Culture Class" but taken to another level (the expert level).
A lot of us are studying Japan at University Level (my specialisation in philosophy was japanese philosophy), so I'm sure a lot of people would be interrested by that.
Many podcasts do interview with skype, so I'm sure it would be no problem for pros like you...
