As Infinispan does only support a fixed number of Commands and I cannot  (and don't want to) add a new command as I am in a different module, I hacked the PutKeyValue: on special key values, my interceptors know that  they should handle it. This way, PutKeyValue is not a put per se, but a way to facilitate RPC and an ugly hack :)
