If I understand correct, FME is also working with (indexed) temp files? I'm not an FME user, so I can bu wrong, but I always wondered what kind of format that is... IF we (as FOSS community) could come up with some (new?) indexed file format, it (besides being a in-between product for transformations) also a potential data exchange format (maybe some zipped version of file+index?)? Anybody into this?
