You probably can use Jython for this.  The "loadBundle()" method's
second argument is a dictionary in the form:
datasource:filename

There is no "fileset" equivalent provided in the Jython IDV scripting,
so you would have to use the Jython library to get a list of files to
use....but, otherwise, this looks quite doable in Jython.

Something like this, perhaps:

import glob, string
list=glob.glob("*.nc")
for file in list:
  loadBundle("${islpath}/test.xidv", {".*" : file} );
  pause();
  k = string.rindex(file, "/");
  fn = file[k+1:]
  writeImage( "${islpath}/+fn");

(not tested, of course....just an idea....)

Good luck.
