Hi -

I hesitate to be the one to say this, and I'm not above suggestive names 
myself, but could we please use a name that doesn't give the impression 
that the IETF is full of college age frat boys?  Say maybe: Q4D?  I 
understand the giggle factor of the name and the implied raised finger 
given to all other curves, but still - this will probably be more 
problem than benefit.

I'm not going to further argue one way or another on this.  But it 
needed to be at least mentioned.

Later, Mike
