Depends on the method. Snapshotting Logic Studio and the older version of Final Cut Studio 3, could be a pain. You'll need to make sure you have a separate 'snapshotted' version for each version of OS X you plan to install on. There might be some frameworks that get installed in /System/Library that have different versions depending on whether or not you are running/installing on Snow Leopard, Lion, or Mountain Lion. If you can isolate those specific files you could package them up separately and omit them from your main installer package, to minimize redundancy and save on storage space. Otherwise, I've had no issues deploying. I'm sure you could script the install as well using the DMG's from Apple, so you don't have to snapshot the install with Composer.
