I want to mention that this example isn't based on any
specific browser. So my use of the OBJECT tag is rather based on
the specification in http://www.w3.org/pub/WWW/TR/WD-object.html as
I expect that netscape or any other popular browser will implement
these features. I want also to precise that all our existing code
is C++ and we want to remain this way.

Erika,
Grail doesn't support <OBJECT DECLARE>, so the single applet that
uses an external source of data would be necessary for your
application.
Does your answer remain the same with this precision ?

It will certainly be dependent on the applet language, and I'd
expect that browser dependencies will also be a problem for a while.
Grail uses Python's keyword arguments to pass parameters to the applet
class constructor, but I don't think all applet languages support
keyword calling, much less the same kind of runtime support that
Python uses.
Ok.

I must say I agree with your boss; I don't either. ;-) There's
clearly a lot of work to be done on Grail's model for applets and
resource declaration. Since Grail is mostly a side issue here, I
don't expect resolutions to many of the real problems in the immediate
future.
