For processed I'd definitely prefer a different file ending to be used - raw should be raw, if it's processed, it should be "processed raw" or similar. Just to differentiate between things that originate from floppies and "tampered with" data.
We are currently doing minor tweaks and fixes to the codebase, then this will be handed over to porters to create libs for OS X, Linux etc. After all is fine, there will be a release. This way we can avoid a back and forth of the codebase...
