Hi Ben:

THREDDS allows you to aggregate along any dimension, including a 
"new" one.  In your case, you would aggregate across time, and then 
do the normal OPeNDAP call for the one location, treating it as if it 
were one series.

You can see a lot of examples of this at:

http://oceanwatch.pfeg.noaa.gov:8081/thredds/catalog.html

All of the Items under the heading  "Aggregation Satellite Datasets" 
are aggregated in just this fashion . You can pick one and go to the 
html interface and see that you can select to get a time series at a 
point.  In fact, you can get a time series for a region.

HTH,
