While I do share your concerns to some extent, I'm a bit more of an  
optimist.  While I personally find XRI's wacky, if they're  
interpretable as the "path" behind some XRI Proxy Resolvers, they're  
not much different than any "normal" URL:

Yeah, it is an extra step, and obviously they won't work as HTML  
anchors, so I wouldn't want to use them.  But, the XRI folks -- and  
the SAML folks -- have been working at this for a long time, so  
there's always a chance they know something we don't, so I'm glad  
OpenID 2.0 is opening up to let them "into the fold."  As long as  
they don't add too much complexity into the core, open extensibility  
seems the way to go.
