Hi John,

One comment w.r.t. one of the points you make below...

I agree with respect to this point.
probably when selecting the locators pairs to be explored, we need to:
- consider the issues included in RFC3484 but probably with a different  
priority
- consider other information, like reachability, preferenes and so on,  
available from the shim6 protocol

I have wrote a mechanism for locator pair selection that takes into  
account this additional issues.

I haven't submitted it yet, but you can find it in:

selection-00.txt

perhaps this could be a useful tool...
