[Users] Improving TLS implementation

[Juha Heinanen]

cesc,

you made a good summary, but in multi-domain case, it is not just a
technical problem on how to present or offer a domain specific
certificate.  in order to be able to do that, the domains have to
surrender their private keying information to a provider that currently
happens to host their sip service, and to another provider that hosts
their web service, and to third provider that hosts their e-commerce
service, etc.  

in most cases, this is simply out of question.  companies are not going
to do it.
