I am interested in using controlport for monitoring, debug, and control of a flowgraph as part of a larger distributed signal processing system. I'm currently running GR 3.7.4 so I still have Ice but the rest of the system uses zeromq. I'd like to remain consistent and I'd like to have something independent of the GR version (Ice seems to have been removed from later versions). The controlport documentation states that it's agnostic to the rpc framework, but I cannot figure out how one would use a service other than Ice. In fact I can't even find where the Ice server is setup in the flowgraph and how the server discovers the registered rpcs from each block. Any suggestions would be appreciated.
