Correct, I think Max's train of thoughts goes down to: could the VFS implement openStream() is such a way that it would look like a JAR stream? When I wrote the visitor, this was really the "common interface" I expected URLs I interact with to implement.

I understand that scanning multiple time is stupid (though some hard figures would be better :o) ).
But how does the VFS provide some ease of use  / dev? I can't find a clear benefit for Joe Pack (though I imagine Max like the concept when integrating into Eclipse).

Exposing an interface is possible but is a decent amount of work. I would like to just the urgency / necessity / usefulness before going that road :)
