SystemWindow equivalent for just one Application?

[Geoff Canyon]

Using the systemWindow property you can make a rev window float above 
all others. What if you only want to make it float above a certain 
application. The goal would be to make a Rev app that functions as an 
application-specific palette.

I think I remember you used to be able to do this with FaceSpan-built 
apps. You had to edit resources (on OS 9) to make it happen, and set 
some resource to the creator code of the app you wanted to float over.

In any case, is that even possible under Windows/OS X?
