When I saw resqgeek's note last night I brought up mapquest and plotted NYC to Charleston. Comes out to a little over 12 hours. I don't like driving that distance in one shot, so I would have to break it into two segments, which leads to four days spent on the road. Unless I end up with a lot of vacation days left over (which I doubt, since I hope to squeeze in more AU/NZ conventions) I think I'll have to fly.
