John Kelsey, chief of something or other at NIST, gave a pretty
comprehensive talk on the NSA issue for NIST at Real World Crypto in
Janaury . My take-away is that they are taking it seriously.
From memory, there wasn't anything directly spotted for the ECC stuff,
but there has been this rising tide of demand for new curves ... so
maybe now is the time.

If you're saying, can the academics stumble across something that the
NSA had beforehand, well, of course. But I'm not sure that's what you mean.

Yeah, curves look much harder than hashes and ciphers. But is there a
