Right, I think we should mention this.  There is no equivalent feature
in GnuTLS yet, but I'm working on PKCS#11 support to address one aspect
of this (client smart card authentication) and made the first release a
few days ago.

Yup.

Oh, right.  I made this clear at the top of the page now.

Btw, I'd like to add other free TLS libraries to the list.  That's why I
made the implementations have one row each in the tables, rather than
having the implementations be one column each.  This allows the list of
implementations to be added easily, without clobbering the page too
much.

Good idea.

Thanks for the support.  I hope people more familiar with OpenSSL and
NSS will provide the appropriate feedback.
