Adding a service to a remotely served dataset

[Roy Mendelssohn]

Hi Ethan:

I am not certain I follow.  To be more specific, look at:

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

and scroll down to the datasets " Remote test to Nomads THREDDS  
catalog", which is actually on a THREDDS server on an NCDC computer.   
They are remotely served through catalogs.  Can we add the WCS  
service on our end, or will it only work if NCDC adds the WCS service.

While I have your attention, I have not been able to get a straight  
answer if there is a way to send the WCS request to get a time range,  
rather than a single time, and if so what is the syntax for that.

Thanks,

-Roy
