"... and we'll keep asserting this until you cry Uncle, dammit!". 
PSKs/passwords are the basis of the most complex, scalable systems ever 
designed.  Just one of these, Facebook, has half a billion users using non- 
scalable PSKs, and exactly zero using scalable PKI.  Gmail, Yahoo, Youtube, 
Flickr, all of these operate on a planetary scale using non-scalable PSKs.  So 
could I make the following modest suggestion, whenever someone wants to say 
"PSKs don't scale", could they either qualify it with "... beyond planetary 
scale" or alternatively "... and I'll keep asserting this while saying 
LALALALALAI'MNOTLISTENING until you go away".

Thanks,
Peter.
