Sorry I wasn't there on Thursday, but versioning is something that 
really appeals to me.

As I understand it the openraster format is to be implemented as a 
ZIP file containing binary files and XML in a folder structure (much 
like ODF).  If applications could optionally read and write this as 
a 'real' folder structure on the filesystem, it would allow some 
nice stuff:

I could open one of my 2 gigabyte multilayer images, change a layer 
attribute, save, and all that would need to be written to disk would 
be a bit of XML.

A multi-file structure would fit into existing version control 
systems much better than a single ZIP file.

Bundling this structure into a 'normal' openraster file for 
transport/archiving would be easily done.
