Instant hot beverages

They already have chemical products that instantly generate heat when properly agitated, largely used for physical therapy -- now it's just a matter of combining that chemistry with beverages like coffee, hot chocolate or whatever. I suppose the key is in the packaging -- making sure the product is easy to agitate and that the chemicals are always kept separate from the beverage. Assuming you could get over that, it sure would be nice to have on hand in case you get caught outside somewhere cold -- don't have to make a fire, just agitate and enjoy a nice cup of cocoa...
