As the title states, is there an equivalent to Click Once application deployment for the Mac?
I ask this because the version of Safari that ships with Lion has removed DMG (disk image) files as a "safe file type" that is opened after downloading. The company I work for has a rather special-purpose application that should launch as soon as it is downloaded.
