Suppose yes. Also, I have to note that there is a modification of SPARQL to query quards (we use SPARQL to query data from CP). Suppose, there possible some incompatibility problems between triple- and quard-based CPs.

Suppose yes for Neo4j, AllegroGraph, Boca. What about InfoGrid, HyperGraphDB - as I understand, they does not support RDFS/SPARQL. As a result, for these DBs we can implement CP with no query support.

There already exists some (perhaps outdated) IdAS CP implementation used XDI endpoint.

Yes, suppose we need to implement base CP with data providers support. Actually, the current Jena CP can be easily refactored in such a way.
