Coming Soon: Altimeter from Mindsensors

Once again LEGO-X has spotted an upcoming sensor... This time it's from Mindsensors and visiting their Coming Soon page  you can read about them making an Altimeter for Mindstorms NXT.

"With an Altimeter, you will be able to measure altitude above sea level."

Sounds like an interesting sensor for NXT projects such as HALE
I wonder what other ideas you may have for an Altimeter equipped robot?
