When i have guests over who are overly sensitive to heat, I smoke a pork butt w/ 1/2 my normal rub and the other 1/2 rubbed with the amount of salt that was in the rub for "my" half. Works great and should work just as well for brisket or ribs.
By the way, I came up with this idea after a Vermonter who once lived in Alaska took a bite of my pulled pork, broke into an immediate sweat and said "wow, this will drive the frost right out of a man!".
