(Remark: JSON-RPC - Update to 2.0? that the supported spec 1.1 is outdated but this is not the major problem)
But the Today world is REST (and not JSON-RPC). See statements as
An in the real business world the companies asking us to provide a REST-Server functionality will not accept JSON-RPC.
Discussions as http://stackoverflow.com/questions/14645022/can-remobjects-sdk-parameters-be-passed-via-the-uri/14648334#14648334 do show that we are not the only ones with that problem.
Now the logical question: REST versus JSON-RPC / what does RemObjectSDK support in the future?
IMO it makes no sense that each one tries to solve this problem by inheriting and adapting some functionality!
