Fair enough. Alternative suggestions? :-)

I don't think anyone would disagree with that.

A quick look through the NANOG historical slideware suggests very  
little mention of Teredo. Again, someone from Microsoft who can fill  
that gap might be useful. And probably someone who's using Miredo (an  
opensource/free implementation).

I've been doing a lot of thinking/writing about deploying these  
things in the real world so I can knock up some pictures+notes, but  
again, better to hear from someone else who's done/doing it, rather  
than someone who's been playing/thinking. I assume there is someone..
