On some occasions you just can't fulfill an entire interface, and for 
whatever reason can't or don't want to create a super interface that you 
*can* fulfill so you do the best you can and raise NotImplemented when 
you can't.

I don't know anything about this situation, so I don't know if that 
approach is warranted here.
