We were not aware of this draft. Indeed, at first glance
it seems quite similar. Apart from formal (e.g. missing code point request, 
descriptions of MIB module and relationship
to other MIB modules, and security considerations) and editorial aspects (our 
description seems more aligned with RFC
3414), I spotted the following major differences

- draft-hartman-snmp-sha2 defines 3 protocols whereas our draft defines 6 
protocols

- draft-hartman-snmp-sha2 does not use any HMAC truncation, whereas in our 
draft, all HMACs are truncated. (For a
discussion of HMAC truncation see our security consideration)

- in draft-hartman-snmp-sha2, the length of the authentication key K is only a 
SHOULD, while in our draft it is fixed.

- our draft defines methods for key localization and key change using the same 
hash function as the authentication protocol.
