"This reminds me of that mountain bike seatpost with a switch that raises and lowers the seat height!"

I don't know about that one, but there is some rig marketed to tri people that moves the saddle. It's here: http://www.m2racer.com/products.php?...products&id=10
The review they link to on their site basically admits that it's just like an adjustable stem, though: use it to futz with your fit until you get it dialed, and then ebay it or parts bin it after buying the piece you really need.

"For some bars, I'd like to be able to adjust the drop on the fly, if that's possible. Sorry this was too complicated for some of you guys to understand."

And barring some mad science rig that you might find on a card table in a 10x10 booth at Interbike, the part you want doesn't exist, and wouldn't be a good idea if it did. If you're not ok with that, again, I suggest college. Sorry if that's too complicated for you to understand.
