Development of Creative Commons licenses

[Keith Coleman <keith AT cs.stanford.edu>]

I've been reviewing the new 2.0 licenses (for inclusion a Stanford CS 
research project) and have noticed some odd interactions between licenses. 
For example:

Let's say I combine a worked issued under a Sampling license with a work 
issued under a BY-NC-SA v2 license. Sampling permits Sharing but does not 
permit Distribution, a condition which is MORE restrictive than BY-NC-SA's 
permission of NonCommercial Distribution but LESS restrictive than 
BY-NC-SA's permission of only NonCommercial Derivatives. (The matter is 
additionally complicated by the unidimensiality of the CC metadata, wherein 
every clause or no clause is affected by things like "requires noncommercial.")

So under which license must I issue my derivative work?

Option 1: BY-NC-SA
But this violoates BY-NC-SA's use-the-most-restrictive clause regarding 
combined works.

Option 2: Sampling
But this violoates BY-NC-SA's use-the-most-restrictive clause regarding 
combined works.

Option 3: Some new mutant license
But this could get confusing from a marketing/biz perspective.

What do you recommend in this case?
