I know that TLS does not depend on DNS or TCP/IP.  My code has no idea
about either of them; it just processes strings.  My objection was to
Martin's belief that SNI is somehow not a part of TLS because it is
"just" an extension.  He implied that if TLS code uses the SNI for
anything other than to pass it to the application, it must be broken.
That is just his opinion, and when I release my code he will have the
freedom to not use it.

This thread is now off topic, so I won't say anything more about it.


P.S. where can I find the spec for BBP/CD?  :-)
