I've just had some feedback from the Hessian people on this. Turns out  
to be an issue in Hessian 3.1.3 with serialising arrays of interfaces.  
They have it slated for fixing in Hessian 3.1.4 and I'll try it again  
in Cayenne after that.

The move from the Hessian 1 protocol to Hessian 2 protocol that this  
upgrade provides will apparently allow a significant reduction in  
message size and therefore speed improvement over slow links.
