Public implementations of SPARQL 1.1 draft features?

Hi everyone,

EricP and I are doing a refresh of our SPARQL By Example tutorial 
(http://www.cambridgesemantics.com/2008/09/sparql-by-example/). In 
particular I want to update it with the latest on SPARQL 1.1 features.

I'm looking for either public SPARQL endpoints (e.g. sparql.org, 
demo.openlinksw.com, or data-set specific endpoints) or (less 
preferably) freely downloadable implementations that support the 
following *in the style of the latest SPARQL 1.1 drafts*:

* Projected expressions
* Subqueries
* Aggregates
* MINUS
* NOT EXISTS (either filter, graph pattern, or both)
* Property paths
* Update
* SERVICE & BINDINGS
* Service description
* Queries with active entailments

If you have or know of any of these, could you please send me a message 
off-list?

thanks,
Lee
