I don't know about being clever, but the problem reminds me of
selling ad space on web sites.
I read a book about it, namely "OpenX Ad Server" by Yilmaz
It provided a lot of back-end considerations for displaying ads, such as:
1. How to randomly preference some ads over others. To give
preference to gold over silver by simply having more gold ads than
silver ads in the collection of ads to pick a random selection. For
example, if you have twenty gold ads and ten silver and randomly
pick, then gold has a a 2:1 advantage even though the pick is random.
2. What time of day show ads per location of user -- you see, each
time zone has it's own "busy" time and ads shown during those times
are at an advantage. For example your web site may be showing one set
of ads for CA, another for MO, and another for MI all at the same
local time.
3. And other such considerations -- it might be worth the cost to
purchase and review. They did a pretty in-depth study of how to track
and optimize ad sales.
