[Oz] newbie question...

[Mahmoud Rafea]

Yes, It is generic. Furthermore, the engineering approach is systematic and
easier to maintain. Notice also that distribution on different machine is
for free.

Regarding performance, this always depends on the application complexity and
the design of the system. In most situations the use of COM or Java is
needed to develop an application front-end (client-side). Consequently,
Mozart as a back-end (server-side) implements the application-logic while
the front-end collects inputs and visualize results. This approach is
effective and very efficient.

If someone puts together a generic mechanism for calling COM objects I would
interested.

I would be interested in why you prefer the second alternative. Is is
because
it is more general? (You could for instance interface with Java-code in
this way.)
What about performance issues? What is the performance difference between
calling C++ code versus packing/sending/unpacking data streams?
