Ah, you might want to have a look at OpenLR - a recently proposed
standard for ensuring that two map providers are referring to the same
stretch of road whilst having separate geodatabases. Primarily aimed
at exchanging traffic data between satnav providers it solves the same
problem we're talking about here - you could refer to roads in
openstreetmap without needing to know their osmid, and it's robust
against moving things around a bit and/or splitting, merging etc. I'll
hold off saying it definitely is the answer since currently it works
in theory but I haven't yet seen it working in practise!
