Agreed. And I notice that Mikel Maron is involved in the  
OpenTransitData project you refer to that is trying to free up this  

A standard licence would of course be a great benefit and I for one  
have scratched my head after reading all the different terms on which  
the different GTFS feeds are published wondering which ones I could  
use for what.

I suggest we start sketching out what that licence should look like. I  
hear the same concerns from operators. I therefore suggest that one of  
the basic terms should be that the user of the data should be  
accurately represented the information and should use current data for  
trip planning purposes etc. The output data should always give an  
indication of the period for which the timetable was valid.

However .... for now we do have enough data for enough places to seed  
the innovation process (with products like Graphserver/ GoogleTransit  
etc) to build the 'killer-apps' that will draw the data out of more  
authorities over time.
