There is also the talk-transit at opentstreetmap.org discussion list, the folks
who are subscribed would be interested to hear your methods/ideas about
this.   Just cc: that list in your discussions :)

http://lists.openstreetmap.org/listinfo/talk-transit

BTW, once the licence is correct, just simply convert the data to .osm
format and make it available to the community (via this list  & making a
wiki page).   & Remind people to only copy in those stops in a small area
(that they know of) and can handle on their own.
Splitting the .osm file into geographical areas small as possible would
really help, or even breaking it down into different types of bus stops (if
that information is available)  would certainly help. (quad-tree tiling)

This method, when combined with other methods,  ie.   WMS layer maptile
overlay / OpenJUMP automatch Diff files.   Is the ideal solution, as it can
involved the greater community, who has varying levels of technical
ability.    The source data doesn't need to be changed, but  it can be
enhanced (externally) by adding in the OSM NODE ID, into the source
database.   So then it can be cross-referenced to ensure quality control.


Cheers,
Sam
