[Serusers] STUN servers?

[SIP]

Until recently, we've been using the Mystun server because it was a much
more stable and reliable version of a stun server than the Vovida
implementation (which hasn't been developed in a LONG time).

The Mystun server, however, doesn't support XOR_MAPPED_ADDRESS or some
of the other new things from the draft-ietf-behave-rfc3489bis-15.  I'm
wondering if anyone knows of any good stun servers out there that do.
