I support this work an can be counted on for reviews.

There is already a published document from the European OMS Group
(Metering), referring to TLS NamedCurved IDs for Brainpool ECC:
http://www.oms-group.org/download/OMS-TR01_Security_v110.pdf (Chapter 7.1,
Table 11)

If no dedicated IANA assignment is available for the Brainpool curves, it is
likely that the "Reserved for Private" use range of the EC named curved
registry (65025-65279) will be used for the TBDs which may lead to future
"Private" Assignment collisions. 

I agree with the proposal to start (in 2013) with 256bit curves and leave
the 192bit and 224bit curves out for TLS.
