we've been talking about this for weeks.  the worst problems with
site-locals are their ambiguity; we need global uniqueness to get
rid of that ambiguity and also to allow them to be reliably routed
between sites.

however we may just be using the words in slightly different ways - 
globally unique vs. probably unique,
site-local (FEC0::/10) vs. some site-specific address space TBD,
etc.

I currently think 

- we need a new address space for globally-unique PI addresses (GUPIs)
  
- some mechanism for ensuring global uniqueness is probably better
  than having those addresses be probably unique

- we need an understanding that GUPIs are not globally routable
  unless/until we know how to make that routing scale - but NOT
  an architectural limitation against it

- use of site-locals (FEC0:://10) should be discouraged in general
  with a possible exception for isolated/test networks
