My AF tree is looking like this: Top Level (UI) launches Data Logger and Controller. Controller launches N number of identical hardware actors each talking to identical hardware (at different addresses). What I need is for the hardware actors to collect data from their respective instruments (inheriting from Timed Loop) and then pass that (somehow) to the Data Logger actor which in this case is neither their caller nor their peer. One user selected hardware actor will also send it's data to the UI for display. I'm looking for the best method for passing that data to the Data Logger and UI. Would passing it up the callee/caller chain to the Top Level UI and then down to the Data Logger be the best method (too many layovers?) or would using an FGV as an intermediary be reasonable?
