Okay.  Thanks for clearing this up.  That causes this to make a fair  
bit more sense.

Great.  This is exactly what I was looking for--some way to preserve  
the simplicity of OpenID as it stands today for those applications  
that don't need anything more than that.

Okay.  My apologies for having made that statement in the first

and the conspiracy theorist in me took it from there.  Again, my  
apologies.  I look forward to seeing the future of YADIS.

Thanks for clearing things up.
