XPath is probably not expressive enough for all use cases, but it's a nice way to express things for the cases where it does work.
As we said, this was only one suggestion for how to do traversals in the REST framework, our main suggestion was sent out a few minutes ago: http://lists.neo4j.org/pipermail/user/2010-March/003224.html , the XPath implementation was meant to complement this main traversal framework. Since it's two different implementations it's nice to keep the discussions in separate threads though.
