[neo4j] QueryResultProxy not Serializable

I'm trying to send a mapped Neo4j query result object (a @MapResult Interface, proxied by QueryResultProxy) over to another JVM using Spring Remoting. Seems the QueryResultProxy object graph is not Serializable. I'm not really sure how the QueryResultProxy works - but I think other Spring AOP proxies are serializable. Is there something I can do other than converting the QueryResultProxy to a concrete object in my service layer? Should the QueryResultProxy be Serializable?
