MDX can graph sensors in real time and log that information for display in Excel or something like that. Advanced calculations can be made on real time data and logged as well, but if you wanted to manipulate data over historical data, MDX cannot do that easily as of now.
I do developement work, and since I develop for the FB already (obviously) I know I can make what you want, but just to let you know up-front custom software is not cheap.
Hardware wise, it seems like a perfect application. If you want some custom software done, send us the details.
