Dear colleagues:

A slight update of my curve representation draft.

Based on some discussions in the hallway at IETF-105, I added another 
example (alternative representation of the BitCoin curve secp256k1 
[Annex M]). I also added a description of how to represent curve points 
pseudo-randomly and added verbiage to the privacy section to alert 
people about this. These changes are informational (I did not ask for 
code points for such a censorship-prevention representation [I could, 
but that is up to the group at large]).

I believe this draft is ready (in fact, I thought it was in May: the 
material above is just bonus material).

If you want to discuss with me at IETF, please do grab me in the hallway 
(I have to leave 3.45pm).

Rene
