So, let's say a proprietary app uses (i.e. exec, fork, and some simple 
communication via stdin/out) a GPL'd app, and won't work without this GPL'd 
app, this would be the point "designed to work with another work".
Sure, it doesn't link, but the GPL'd app is more or less a core part of the 
commercial project.

If you say "rather creative", does this mean, that this kind of usage 
really doesn't create a copyright problem (at least in europe) ?

At least I could understand this argument quite good.
