Chaz'z Homework (you know you want to do it)

[desperance]

Okay, people. I have to do panels at the weekend, for BayCon, and we all know how confident I am in my articulacy, knowledge, memory etc. So help me out here. Particularly, one panel is about alternative lifestyles in SF & fantasy, "from Ethan of Athos to Heinlein's line marriages". So we've got those two covered. What else should I be talking about? (It's very likely that I have actually, y'know, read it. It's just that as soon as someone starts making lists and asking questions, my mind goes sensationally blank. And stays that way. I've been thinking about this for a week...)
