It would be a great idea to add scripting support. In this way it would easier to setup cases that requires repetitive inputs and also it would be possible to run parametric studies.
Edit: Caedium v5 has Python scripting.
I have just this scenario at the moment - doing things more or less manually by scripting OpenFOAM ("OpenFlow") from cygwin, as the cluster I'm using runs Windows...
Caedium v5 now has Python scripting.
