I've been thinking about Micro Four Thirds, which in many cases encodes distortion and chromatic aberration correction into the raw files. But, the raw processor I currently use (Bibble) ignores this data, and I'm having a hard time figuring out what software does use it - for example, does Lightroom use its own database (as Bibble does) or the data in the raw files? Bonus points for info on Linux software, but I'm to the point where I'm willing to switch to Mac or Windows too.
I would also be reasonably happy if there were separate software that could create profiles that I could import into Bibble (specs for that, and it seems like the parameters are fairly standard). Since it would be easy to create corrected and uncorrected JPEGs (using Bibble and in-camera, respectively), that seems like it could be straightforward.
