It Is Compatible/Works. View NX 2 is a bit wonky, though, in that it opens two of the same window (one smaller than the other) when first launched, but, if you click the little red (upper left) button it will quit, then, if you launch it again, it works fine.
MacBook Pro with Lion 10.7.2. --also worked with 10.7.1 the same way, BTW.
