In the github repo, there is a girlpower patch for Reaktor (similar to what lasal and StiX made, but imho much more flexible, yet simpler).
Your “one place” would be the Safe (which holds all the data), and with Read or Split you can noodle down from there (or make Send/Listening combos without links).
In the girlpower folder, there is also an example for TouchOSC, which should also be of interest, on how you make do without AvoidNil, S+H, AsValue/AsString and Stallone.
