You're making the assumption now, that ALTO will need to add proxies  
or intermediaries ("will almost inevitability").  I don't really have

cases right now.  Do you have anything specific in mind?

These are good architectural principles to remember while writing and  
reviewing drafts, assuming they can be followed without falling into  
the trap of designing the be-all and end-all system.
