If you're going to put support in the editors, what about a relation
between an intersection node and one or more ways?  You click the
intersection node, hit the stop sign button (or type highway=stop),
and then you click on the ways to toggle the stop sign on or off (at
which point perpendicular stop lines appear on those ways before the
intersection).  If a way has to stop before approaching the
intersection from one direction but not the other (relatively
uncommon), you split the way.

That's not an immediate solution, but seems like a good long-term one.
 Optionally, the actual physical location of the stop signs could be
mapped as described by MK and added to the relation (they would be
optional, and probably not used for routing purposes but could be used
for mapping purposes, especially 3D/2.5D navigation).
