Since there are 4 billion possible creator ID's, I don't think we're in any
danger of running out of them (of course, that is probably what people said
about Y2K, too). A more acute problem: imagine what the delete application
dialog box, or the Launcher program would look like with 1000 programs
installed.
A loose idea (never tried in practice, at least not by me): Could you store
the apps as databases of some other type and then use DmSetDatabaseInfo to
set the type to 'appl' and the creator to (whatever you want) when you need
to run the app?
If you want all the programs in the same database (1000 databases can be
hard to manage), perhaps you could create an application database "on the
fly" and copy the program there.
