Yes, I like this wording better.

They are required by de facto, not by a pure standard, to support HTTPS
because no commercial vendor of HTTP servers would introduce a server
incapable of providing the capability for internet commerce.


Its like I was saying a previous message about TCP, you don't design
a protocol for the easy case, you design it to scale from the easy
to the more advanced, which is why, yes, for an intranet application,
you might need HTTPS, but that scenario doesn't deter vendors from
including it in their product, because they're not interested in 
rolling <N> different products to support <N> different scenarios.
Just ship one product that scales nicely.


HTTP 1.1 will probably require digest authentication, so if IPP
is implemented over HTTP 1.1, then this would be a requirement. This
is one of the reasons why I'm not so sure it would be overly
burdensome to require IPP servers to support MD5 digest authentication,
whether its used by HTTP or SSL3/TLS.

I'm curious why this would be misleading...
