Road Shifters, Mountain Rear Derailleur?

I'm looking to build a hardtail mountain bike with drop bars for commuting, touring and some occasional light off-road adventures.

Are 10-speed Shimano brifters like the Ultegra ST-6600 compatible with the 10-speed Dyna-Sys XT derailleurs?

+1 for teaching me a new word: brifters = brake / shift levers – Andy Dec 5 '11 at 13:35

In a word, no. Different cable pull ratio on both systems. You can check out this question if you want a slightly more verbose answer.
