Thank you kindly, TLaukkan for a patch that:

Added support for loading bare asset binaries (as opposed to 
xml encoded asset base) to both sandbox asset service and cable beach.
* Added support for enabling region asset service when mxp is enabled.
* Moved base http server content type defaulting before invocation of 
request handle method to allow for variable content type in the response.
