I have a idv-based jnlp-distributed app which includes
-bundle http://localhost/app/bundle.xidv
as an application argument.  The codebase is 
http://www.unidata.ucar.edu/software/idv/webstart, i.e. I am not 
hosting the IDV app itself, just the jnlp file and the bundle.
My app has stopped working.  Now the splash screen is just grey, the 
Java console says nothing.
I see that IDV has been updated to 2.0.  I think that my bundle file, 
created by saving a bundle out in 1.3b2, is now incompatible with the 
code.  I guess I have one of two options:
1.  create a new .xidv bundle using 2.0
2. host the IDV app myself, so I can guarantee that the codebase and the 
bundle .xidv file are always compatible.  Then I miss out on the latest 
idv features (the dashboard is WAY cool!)
Comment welcomed
