Federated Queries with SPARQL

[Massimiliano Collavo]

Hello All,
Is it possible make federated queries with ARC?
like this:

PREFIX foaf:   <http://xmlns.com/foaf/0.1/>

SELECT ?name

FROM <http://example.org/myfoaf.rdf>

WHERE

{

  <http://example.org/myfoaf/I> foaf:knows ?person .

  SERVICE <http://people.example.org/sparql> { 

    ?person foaf:name ?name . } 

}

or it is only possible with apache jena?

Thanks in advance Massiniliano
