[jdev] S2S questions - from attribute and version support

[Norman Rasmussen]

Version=1.0 only requires the server to support features (rfc 3920,
section 4.6), it does not require the server to support tls or sasl. 
My guess that is that if the both servers support TLS (via features)
then do TLS.

Just because you have TLS doesn't mean you don't have to dialback. 
The only time you SHOULD not do dialback is when you've authenticated
via SASL. (rfc 3920, section 8.1)
