Just tried this in Mac OS X Server 10.2.8.  You get a pretty generic "The application could not launch because this system is incompatible." message.

Unfortunately in 10.3.9 it's still broken :(  When you launch the app, it will bounce once or twice in the Dock and then just quit.  You never see any message.

Agreed.  Assuming 10.4 did indeed fix this, the feature will only start to be useful if you then require 10.4.1 or later.


Hmm... If the software is ultimately being delivered in a .dmg, would it be possible to launch some script when the image is mounted?  I've never done something like that.  A shell script (or perhaps an AppleScript) could run a query and post a meaningful message.
