Excuse me?!?!   JAR is used by every Java implementation in

Java is not exactly what I would call well established, but that's not
a relevant argument here.
One issue we should at least think about with JAR is that since it *is*
the JAVA library mechanism, there is perhaps a risk of allowing virus writers
to attach bits of JAVA executable in what *appears* to be a GIMP image.
This is the kind of thing that email virus writers *love*.

Whilst I can't quite see how this would be a problem, it might be better
to just avoid the risk.

	If you don't open up the JAR file with a Java-based tool - 
you can't have Java executing.

	And even if you DO use Java to open up the JAR, nothing 
auto-executes - you'd have to manually kick it off.

	SO even if someone were to put Java bytecodes into a GIMP 
image file, it would never get executed...

  It is very sad to see that Sven thinks that Robin Rowe is the only 
  person to whom his ideas should be told.  Pity the rest of the GIMP 
  developers (current and future) who might like to comment on it.
 
 Use the list archives. Search engines let you restrict to servers. And
 IIRC basically it was about packing XML and some common image format
 like PNG into a some common archive format like TAR, so while not all
 soft will be able to open it, at least the user will be able to
 dissasamble it and load things by hand.

I am currently working on some code related to how GEGL works/is going
to work in cooperation with gimp, bundling complete projects in a
folder/tarball could be a good idea for this as well, my current format
