This is why I use /124s - so all my transit networks end in 
  "...:xxx1/124"
  "...:xxx2/124"

- just convenience, and no fundamental difference to the /112.


Nevertheless I want to point out that there seems to be concepts in the
works (IPSEC with encryption based on the lower /64 bits of the IPv6
address) that might result in the need to renumber ptp links done with
/126s, /124s, /112s or whatever.

There was a big and heated discussion on the 6bone list a year ago or so,
so for those interested in this matter, read it up in the archive!
