[riskable]

I don't think the intention is to "increase the amount of code" but that's what always ends up happening! You're definitely on to something here with JSONScript but it's missing "something". That killer feature that immediately indicates to the developer/end user, "Yeah, that could definitely make my life easier."

I've implemented something similar with my own projects in the past and I think others have and ultimately will as well. "What problem causes us all to ultimately implement something like JSONScript or JSON RPC?"

I think there's two problems and I think JSONScript went a bit too far/got too specific as to how to solve them:

    1) How to specify (multiple) destinations when delivering API requests and their order of execution.
    2) How to execute actions safely despite potentially dangerous payloads.

I suggest removing the "path" part as it can easily be included in the top level of the object (e.g. {"someapp: destination": "payload here"}. I also suggest removing the "get" and "put" nomenclature. That's so old fashioned and synchronous :) . Shouldn't such things be determined by the destination functions?
