I do not support putting TLS into TCP.

It is a heavyweight, one size fits all, baggage laden protocol.  Putting 
something complicated and baggage-laden into TCP is going to harm the 
overall goal of TCPINC - get some lightweight opportunistic encryption 
out there where we can, because the alternate is no security.

 From an engineering perspective, putting TLS into TCP increases the 
chances of no security, IMHO.
