This is a recurring question. The answers invariably are:
- yes it could be done at compile-time, generating N version of the
application and choosing at runtime which one to use (i.e. in the JSP
or servlet or whatever that serves the HTML host page, generate the
appropriate <script src=""> tag)
- you'd have to handle security on the server-side anyway, so you
could also have a single app that just doesn't show some tabs,
buttons, etc. if the current user is not an admin: the "screens" and
GWT-RPC (or whatever) are present in the code, but are harmless
because the server will reject calls to admin resources from non-admin
users.
