Hello,
 I've submitted the following draft:
http://datatracker.ietf.org/doc/draft-mavrogiannopoulos-tls-more-extensions/

It adds two TLS extensions, to solve two issues of the TLS protocols, that
I believe they should be fixed. These are the:
* Short finished message signature fixed to 12 bytes.
* TLS version negotiation (fallback protocol is implicit).

described previously in [0]. In the document I give more detailed
description and rationale of the problems. Please consider
them to be included as WG items.

regards,
Nikos
