What about (I'm just brain-storming now) some graphical way? For example 
right click on a wire, then "add to net class...", "remove from 
netclass..." - something like that?

For impedance matching too... however checking 'maximum' distance would
be a little complex/expensive. Maybe only if explicity requested.

Layer constraint *could* be useful for some applications; the
'programmable' constraint interface could also be considered (either in
table or in python call form).

At least netnames without polluting the sheet with label should be the
minimum. Netname to netname association would be useful but not truly
essential. It's more or less shifting the dialog from pcbnew to eeschema
and extending the netlist, anyway.
