Recently (as in, over the past few months) the WMATA BusPosition feed has been behaving anomalously.
There are three observed problems:
1. The feed doesn't include the entire fleet - during the weekday rush hour we'd expect to see close to 900 buses, but this morning the feed returned fewer than 250 vehicles.
2. Bus positions return the wrong trip, or are lagging badly. Look at this example:
<BusPosition>
<DateTime>2013-08-16T07:32:01</DateTime>

This Gist contains a script and supporting files for building a OneBusAway GTFS bundle with data for all agencies in the Baltimore/Washington area that have publicly released their data.

Configuration parameters come from two sheets in a Google Docs document:

https://docs.google.com/spreadsheet/ccc?key=0AvrkbWHnoksNdGdYam4wX214SXpoRmdia0FEalZvUHc&usp=sharing

The dependency on Google Docs could easily be removed by removing that part of download.sh and using a locally-maintained CSV file instead.
