 Actually, yes, there is an interpolation rule :-) Here numbers don't have to 
end in 0 like in Norway, but other than that it's a similar system, the 
number tells you the distance in meters from a starting point (usually one of 
the four main roads which begin in the main square). Every lot on a street 
has a number that has to be odd or even (depending on the side of the road) 
and within a range, which is usually 10 meters (the common lot size in 
cities), though lots can of course be of other sizes (my neighour has a 20 
meter wide lot, for example).
 In any case, I see Karlsruhe schema and interpolations systems like the one I 
proposed as complementary, neither fully replaces the other, for embedded 
systems the interpolating system is a lot easier to work with, IMHO, and I 
think embedded systems are a very interesting audience for OSM :-)
