It seems that many sites that use ECDHE with various CA signature algorithms 
(ECC as well as conventional symmetric) use the secp521r1 curve - aka P-256.  
I just checked and gmail/google accounts use it too.

Markus showed secp384r1 (P-384) in his example.

The thing is guys that both of these are shown as 'unsafe' in the 
http://safecurves.cr.yp.to tables and are of course specified by NIST and NSA.

Thank you both for your replies.  I need to read a bit more into all this 
before I settle on a curve.
