Hi Dave-

> when a user clicks on the bundle, Java Web start kicks off, downloads

Save the IDV JNLP file at:

http://www.unidata.ucar.edu/software/idv/webstart/IDV/idv.jnlp

to your local disk and use this as a template.  For each bundle,
you can create a JNLP for that by replacing:

       <application-desc main-class="ucar.unidata.idv.DefaultIdv"/>

with:

       <application-desc main-class="ucar.unidata.idv.DefaultIdv">
             <argument>-bundle</argument>
            <argument>%bundlelocaion%</argument>
       </application>

where %bundlelocation% is the URL of the bundle on your web site.  You'd
just have one of these for each bundle that you want to serve up.
You can use any of the IDV command line arguments in the bundle file.

For those well-versed in scripts, you could just have the
URL's point to a web service which would replace %bundlelocation%
with the appropriate bundle URL on the fly.  That would be more work,
but be more flexible.

Alternatively, you could load the bundle into the IDV and use the
File->Save.. menu and save it with an extension of jnlp.  That will
create a JNLP file with the bundle base64 encoded in it.  Then just
point to the JNLP file from your web page.  The downside is that
since the bundle is in the JNLP file, you can't easily replace it.
