[Imports] Mass Bus Data

I created a wiki page explaining the tags here <http://wiki.openstreetmap.org/wiki/MassDOT> http://wiki.openstreetmap.org/wiki/MassDOT
    On second look it seems that very few of the current train stations (less then 20) have additional data that it would make sense to keep the other ones seem to have either no attributes beyond massgis import and highway=bus_stop, or have a bus route reference in in one of many different ways.
The file I made is here http://dl.dropbox.com/u/37626989/mbtabus.osm.zip where do folks suggest I go from here?

Oh and another reason to have others look at the data before uploading is to make sure the tags are correct, no incorrect mappings, etc. Many eyes help to catch this sort of thing.
Thanks for being involved!

I'm getting ready to upload the bus data.
It seems some people already started putting in some bus data (there are 109 that look to overlap my data), is there a way to update/delete these/make them invisible? While some of them look to just be out dated dumps from massgis others look to have work put in.   (for reference there are 8057 stops that I'm about to upload)

By upload do you mean to the OSM database or to a file host for other OSM contributors to download and merge? Hopefully it's the latter, so that the OSM community can look at the data, the tags, etc and can help with the process. We certainly don't want to just delete the existing 109 stops, but rather update them with the new tags/position (if appropriate). While somewhat tedious, merging 109 stops (with JOSM's merge command) won't take too terribly long, and is a crucial step to take. If you don't wish to do this step, then consider uploading the data for others to use.

I started a conflation plugin for JOSM [0] intended exactly for this purpose, for my county's bus data (~4000). The algorithm works quite well, but I got stalled when designing the user interface for reconciling differences. I'd like to finish it but like Ian said, I've been too busy in real life to continue at the moment.
