Comment (by jelte):

 Replying to [comment:13 stephen]:

 > This suggests that we need to add the ability to send message upstream
 with no EDNS0.  It also suggests that the NSAS needs to be extended to
 include a record of whether a nameserver has EDNS0 support.

 yes i sort of mentioned this earlier (comment 2), and not just for non-
 support of the OPT record. I think we should also have a fallback scheme
 for MTU problems and DNSSEC lameness (and possibly other things as well).
