Up to now I have not been able to define an AGS StreamServive as an input to a GeoEvent Input Connector.
With this functionality it would be possible to receive an output stream of geo-events at another server as an input stream.
Smart "chaining" of servers will be possible then.
I think the current existing two "subscribe" input sockets are missing the specific "subscribe" protocol,
because the input counts remain 0.
As a start, receiving a stream of points would be great.
like filtering by bounding box, filtering by query, selecting fields, all types of features.
