Then we agree that we want only one solution.

I read the poll as being agnostic on the question of what the one 
solution would look like.  Given that there are at least two solutions 
that seem to work (and are now quite similar) on the table, I would 
expect a fairly typical process for getting to one good solution.

Yours,

Joel
