Personally I am reasonably convinced by the arguments being put  
forward that any sort of collection of timetable data may be open to  
challenge within Europe under the DB directive. I notice however that  
lots of PT data has been released in the USA under freedom of  
information act which is a curious thing to have to do to find when  
the buses run. For example
http://www.gtfs-data-exchange.com/agency/port-authority-trans-hudson/

I suggest that this is another reason to keen the PT data separate  
from the OSM data.

I was wondering however, if any of the authorities in gtfs-data- 
exchange would mind their data about the positioning of bus stops to  
be imported into OSM. Might be worth asking them at some point. The  
current bus stop positions are sometimes not that accurate in the  
official data. The data for Davis often puts bus stops in the middle  
of houses for example.
