OpenID status update

Trying to move the version number issue to closure.

So it's inevitable.  If you put it in now, and you make it optional, 
then you force
the ID servers to do work now rather than later.  The cost is some slow 
down
now.  The benefit is that the first revision will be a _lot_ smoother.

I think this is a red herring.  The purpose of the version # in the 
protocol is
to be sure that partners can rendezvous at a protocol definition they 
both
understand and - much more importantly they can know when they don't
have a common language.

I think you want it now.  You can go to market faster if you know that 
the
upgrade to version 2 is likely to go smoothly.

Finally it's a signal to the adopters that a version 2 is entirely 
likely and
hence that this isn't a dead end if it turns out something is seriously 
wrong
in version 1.

Just use a integer, the whole major/minor thing isn't useful - as you've
said.

That said, your the BD and I'm not passionate about his aspect of the
design.
