Yeah, from my POV reverse engineering a file format should be OK as long as you own the data contained within. That is why it is OK for people to reverse engineer all of microsoft's proprietary data formats to open word docs, etc. Of course IANAL either and there may be a EULA for the Garmin data that says you can only use the data with their software which would pose a problem. I have never actually used the Garmin software so I don't really know much about it. I can't even get at the data as it is in windows CAB files. Anybody know of a unix tool to browse/extract CAB files so I can at least poke around at the actual data?
