Is this in some way significantly better than using normal REST APIs to communicate? It seems to me like we've been through various RPC's in the past (SOAP, XML-RPC, etc.) and REST has generally proven the simplest and most interoperable solution for APIs. Unless you have a need to really optimize and tweak the performance.
