Yes, it's simple and that is the problem with it, it's too simple.

1) How do you represent the variables, their types and ranges ?
2) How do you avoid inconsistencies (possible sig11) when the node 
   changes the available variables and their ranges.
3) How do you signal changed values. Rechecking all structures
   for changes isn't a good idea.
