I'm not convinced about it either. My gut feeling is that this is not the 
right approach, but I don't really have any better ideas at the moment.

Xander can you give a short description of how this information will be used 
by an application? Would having a label property for the channel also work 
for you (e.g. in_voltage0_label)?
