Re: [tae] The internet architecture

Yes, that is indeed where the world is going.

My point is that it would be nice if the IETF had a means of guiding the outcome here through an appropriate statement from the IAB.

Legacy applications are legacy. But we can and should push new applications to use SRV based connections or some elaboration on the same principle. Even with legacy applications, MX was a retrofit to SMTP.

This certainly seems to be the way that "modern" APIs are heading. If 
I'm not mistaken, Java, PHP, Perl, Tcl, Python and most other 
scripting languages have a socket-like API that does not expose IP 
addresses, but rather connects directly to DNS names. (In many cases, 
they unify file and socket opening and specify the application 
protocol, to, so that one can do fopen("http://www.ietf.org <http://www.ietf.org/> "), for 
example.) Thus, we're well on our way towards the goal of making 
(some) application oblivious to addresses. I suspect that one reason 
for the popularity of these languages is exactly that programmers 
don't want to bother remembering when to use ntohs().
