I'd be interested to hear your opinions on exactly how rpki in its current
implementation would have prevented the optus/telstra problem.  Could you

Here's a quote from draft-ietf-sidr-origin-ops:

   As the BGP origin AS of an update is not signed, origin validation is
   open to malicious spoofing.  Therefore, RPKI-based origin validation
   is designed to deal only with inadvertent mis-advertisement.

   Origin validation does not address the problem of AS-Path validation.
   Therefore paths are open to manipulation, either malicious or

An optus/telstra style problem might have been mitigated by an rpki based
full path validation mechanism, but we don't have path validation.  Right
now, we only have a draft of a list of must-have features -
draft-ietf-sidr-bgpsec-reqs.  This is only the first step towards designing
a functional protocol, not to mind having running code.
