I already have the necessary draft 90% complete, you don't need a rev of TLS,
just an extension "would you like to do encrypt-then-MAC" in the client hello,
and a corresponding "yes, let's do encrypt-then-MAC" in the server hello.
Works with any version of TLS.  I'll post it in the next day or two.
