Climate Control for your shop

The thread about the movincool air conditioners has gotten me to thinking about fully climate controlled shops. Setting aside what I presume to be a huge cost issue, wouldn't the "best" situation be a fully air conditioned shop with adjustable humidifiers and dehumidifiers?
Cooler air in the summertime would be a really nice thing to have (more comfortable work environment possibly leading to increased ability to attract and retain good employees), but I'm really more interested in the idea of controlled humidity. If you could set the moisture level of your shop to that which is dead in the middle of the average fluctuation for a given region, couldn't you eliminate fully 50% of the potential wood movement? Or maybe you could set the humidity deliberately high when you glue up raised and fielded panels so that you needn't worry about an expanding panel cracking the frame.
Do you think that there would be any "real" benefit? From a marketing perspective you could sort of talk it up a bit I guess....
Just wondering.
