And if you be a Python user, M2Crypto exposes ECC and the rest of OpenSSL to your program.

Does 'openssl s_server' support this? Are there public ECC TLS
implementations this is known to interoperate with?

OpenSSL s_server is a test tool, not an application. In 0.9.9 snapshot
builds, s_server support ECDSA, just point your cert and key files
at an ECDSA cert and private key. I have not checked whether it has a
command-line option to select an EECDH curve, but this is not important.

The command-line option is "-named_curve", and if no curve is specified "prime256v1" is used by default unless the "-no_ecdhe" option is supplied
(in which case any name curve is also ignored).

So, for what its worth, s_server and s_client fully support EECDH
and ECDSA.
