You wouldn't be able to charge the full "in market" rate, but you could have a "BYU market" rate where the subscriber fee is the national rate + % of LDS in states located west of the Rockies.

So, lets say the national fee is $.10, each subscriber in the Western states would pay the following:

Idaho ($.36)
Wyoming ($.22)
Nevada ($.16)
Arizona ($.16)
Hawaii ($.15)
Montana ($.15)
Alaska ($.15)
Washington ($.14)
Oregon ($.14)
New Mexico ($.13)
Colorado ($.13)
California ($.12)

It would be a way to define the "BYU Market" without mandating full in-market charges throughout the Western states.
