It's an important point and outlines the differences in Mozilla's approach. The same applies for Mozilla Persona. The cost of openness is building a system that's loosely coupled and then adding the glue afterwards to make it easy for many.

It's quite the opposite of closed systems and you have to see the longer term vision to understand why Mozilla starts out with this type of solution.

@chrismorgan, it might go a long way to include the plans for a "hosted" version of the open model as a convenience layer. Most won't make that leap themselves.
