which rfcs? I can find a draft in softwire:
   http://tools.ietf.org/html/draft-mdt-softwire-map-translation-01

and a reference to this in wikipedia:
  http://en.wikipedia.org/wiki/IPv6_transition_mechanisms#MAP

which says: "...(MAP) is a Cisco IPv6 transition proposal..."

so.. err, we won't see this in juniper gear since:
  1) not a standard
  2) encumbered by IPR issues

weee!
