We're a small managed services provider, and we started doing  
authenticated SMTP with TLS on port 587 six years ago.  It's at least  
in kindergarten :-)

Once we explain the advantages, our customers love it since their  
email "just works" pretty much wherever they go.

As a former manager for a small resnet, blocking port 25 outbound is A  
Good Thing.  Cut abuse email down by a huge factor.
