URI Template experience

It's been a while since the URI Template draft has been updated, and
in the interim
there has been some implementation experience:

   http://blog.springsource.com/2009/03/08/rest-in-spring-3-mvc/
   http://code.google.com/p/uri-templates/wiki/Implementations

In the intervening months two things have happened:

1. In all the URI Template examples I've seen, only the simplest case {foo} has
   even been shown.

2. I've been repeatedly asked about "going the other way", i.e. parsing URIs
   based on templates.

This leads to two questions:

1. Are there any real-world uses of the more complex URI Templates, or
is {foo} enough?

2. *If* the syntax is simplified to {foo} there is an opportunity to
support the parsing
   case, ala http://bitworking.org/projects/1812/wsgidispatcher.html
    Is that of interest to anyone?

  Thanks,
