I just cut into a parma that has been aging for a few days over a year (made on 4/14/14). As you can see in the first picture, I had waxed it after two months or so -- it was not large enough to feel comfortable leaving it unwaxed for the whole year. Also in the picture, you'll see a little flaw in the wax (lower right) where a bit of mold got it; this had created a small soft spot. But other than that ... as you can see in the second picture, it turned out extremely well. Still sliceable, but also grates well. And the flavor -- wow! Even without any lipase, it has that nice parma tangy-ness. A success!
