That looks like a huge improvement from the existing proposal. A few 
questions for clarification and discussion:
* In this proposal, the actual TMC LCDs are not technically required, 
are they? If all the ways are tagged according to this schema, you can 
look up the segments just by looking at the ways? I guess having the LCD 
encoded onto nodes will speed up lookup.
* How do you plan to make this huge effort (even just for Germany) 
manageable? I mean, it's simpler than it looks, but it still is a *lot* 
of work. A JOSM plugin? A dedicated website to track progress and show 
bugs / inconsistencies? Other supporting tools for mappers?
* Do you (or anyone) have any info on the 'openness' of this data in 
other countries? I believe they are proprietary data here in the US, not 
sure though (will ask in talk-us).
