given his political statements, but Victor Davis Hanson could be interesting. His main focus these days is military history in ancient Greece, but he's also covered agrarian life and he co-wrote "Who Killed Homer" about the death of Classics in modern education (I remember talking about that back at AS).

He seems to be fairly tech savvy, since he maintains a website (victorhanson.com). I've been able to find this info for his speaking engagements:
