That's right. I don't know if a month is the ideal time, but we can think that way for now. I'm not sure how we'd scramble it for the following month, either: maybe increment every exchange by 1 on the list. If Al and Bob exchanged in September, then Bob would exchange with Chuck in October, til we got to Zach, who would exchange with Al.
