Zipped apps are common way to publish apps :) OS X can unzipp them and users
can run the app. Another way is to make a disk image (DMG) and place the app
in the disk image. Compressed DMG has the size close to a ZIP archive, and
can have nice installer (a.k.a. copy to Applications), readmes etc.

15MB Zipped is the "ok" size :)

As for the PyQt4 installer - you have to compile it, but the final py2app
made app doesn't require for the user to install anything. The app will run
on it's own :)
