So how would you convert the distance you moved into damage?
So the point of this is simply to move fast. Can you convert this into damage?
I saw Cometary Collision in Sky's link but that doesn't actually give you damage according to how far you've moved.
You're not falling so falling damage doesn't count.
And as for your other discussion, I have a RL DM who has banned TOB and Psionics.. Much to my protests and the entire groups lack of understanding both. I believe this is generally the reason why DMs ban them. They haven't taken the time to learn the rules behind either.
