+1.  Like I said, this fits well with the goal of "flexible  
indexing" (which should also be called "flexible scoring" or whatever)  
so those are things to keep in mind.

Have a look at the How To Contribute section on the wiki and keep in  
mind that small incremental, back-compatible patches are often easier  
to swallow than very large ones that massively change things.

At any rate, what you are proposing is very interesting and exciting  
(to me, anyway).
