Ok, did you have specific ideas on how to integrate support for different
coordinate systems? If yes, I'm happy to go the suggested way, else I need
to come up with ideas myself.

Also, were there ideas on how to actually support something like AMR? From
the current code I see that reduction operators for doing the neccesary
interpolation do not exist.
