I've heard that wrapping firm-hard cheese in a J-cloth damp with vinegar preserves it longer.

How long do you need to keep it?  I routinely bring cheese on 10-day trips and make no special effort to keep it refrigerated or otherwise preserved.  Never seen a speck of mold yet.

I've brought many different jacks, colbys, swiss, and flavored versions of same.  They all keep very well.  I just keep them wrapped in foil and put 'em in a ziploc.
