What about doing it differently altogether? Altium, and AFAIK many other 
high-end and midrange tools, allow you to tag nets with properties in 
the schematic editor. We could have a net property for this instead.

(To be accurate Altium uses a combination of these.)

I'd happily implement the net tagging, though it'd require a bit of 
brainstorming from everyone on how those tags should be stored and 
shared with pcbnew.

They could be used for other things too - first thought: net classes.
