I wish you would make Eye-Fi Helper to be compatible with Linux/Wine. I think this shouldn't be too hard since I can get the Helper application to run already with Wine, just won't let me put any settings to it. (Tried replacing the xml-file, keeps overwriting it)
EDIT: I actually got this to work by copying also the master.db and EyeFi.log (as with the settings.xml), still gives couple errors in the console, but it works and I hope it will keep working.
EDIT2: Was too fast, it still keeps losing settings, got it to upload one picture, so this shouldn't be a big bug.
