Hi, Jeff, 

Thanks for your quick reply! The information you provided is very
helpful! I have several more questions which are included inline.

This feature is exactly what we are looking for. When do you think this
would be released? Would there be a beta version that will be available
sooner?

Actually I also tried with the catalog link on THREDDS project page
(http://motherlode.ucar.edu:8080/thredds/catalog.xml) and received the
same error, although it worked with the two default THREDDS catalogs in
the IDV drop down menu. My IDV version is 1.2. I installed it using
InstallAnywhere. The call stack is as follows:
java.lang.NumberFormatException: multiple points
 at java.lang.FloatingDecimal.readJavaFormatString(Unknown Source)
 at java.lang.Double.valueOf(Unknown Source)
 at java.lang.Double.<init>(Unknown Source)

Is this a bug?

Could you please explain a little more about the http based access? What
needs to be done for this approach? Since our goal is to provide the
Level-II data to the public instead of just researchers at Purdue, the
shared file system solution probably won't work here.

Thanks again for your help!
