What if in the not too distant future the demand for .bit domains takes off to the point where people are willing to pay far more for Premium names than their regular registration/renewal cost.

The approach outlined by Noel Tiernan would work just fine for the community.

If you work off of this all that's needed is to add NMC support and to support the swapping of names in place of currency.
