Comment(by nickm):

 If [http://www.imperialviolet.org/2010/12/21/eccspeed.html agl's numbers]
 are right, P224 would be much faster than P256, and secure enough for us.
 But before we get too deep there, we need to check what (if anything) our
 choice of curve will do to fingerprintability here, or whether our choice
 of ECDHE ciphers at all will make us fingerprintable.  In the latter case,
 maybe bridges should disable them by default when not using a pluggable
 transport.
