Will Minecarts be like Lava Boats?

Notch has suggested making minecarts act as if they are lava boats. How cool would that be to finally have a way to get past the lava oceans in the Nether! That would make it so much easier to explore the Nether! I bet though that this is in the very back corner of Notch's mind so it might not come out for a while or at all. I want it though so bad! Lava Surfing!
