I would be interested in defining a chain of processing steps that  
lead from an OSM file to the binary indexed whatever structure, and  
then find the point in that chain where a lot of the "expensive"  
processing has already been done but decisions about the final format  
are still open. Some kind of "intermediate routing graph format".  
This would then be a format which would make sense to offer in a pre- 
computed form on a web site; users of specific navigation software  
could then download this file and apply the last steps to it to make  
a proper indexed and compressed data file for use with the specific  
application.

I don't think that we'll manage to find a "final file format" that  
many routing applications will share.

Bye
Frederik
