I'm curious as to why this needs OSX 10.7 on the Mac? Did they change to a new version of DOSbox that requires 10.7, and if this is so, I hope that doesn't mean future Mac releases will need it.

There are a lot of folks stuck on 10.6 because we need to run old Mac software, and I'd think we're probably more common in the 'wants to play old games' segment than the Mac population at large. :)
