>But EKE cannot be used with elliptic curves

Speaking of PAKE for ECC, from reading a writeup of PACE (for passport EAC) a 
while back, the claimed reason for introducing PACE was that a lot of standard 
DLP PAKE mechanisms aren't secure when used with ECDLPs.  OTOH this RFC 
proposes a complex protocol for ECDLP use with no explanation of how it's 
derived, what its security properties are, or why it's secure.  What's the 
security argument for it?
