DLLs

Hey, here's a question I know some-one can answer -

I wish to provide the same functions (import and export) for different
customers where each customer has a different transfer protocol.

I have all the different protocols in the App and the setup selects
the appropriate protocol for the installation.

Question: Can I put the different protocols into different DLLs
(thereby reducing the EXE size) and distribute just the one dll to
each. I suspect all the DLLs will have the same name so the App can
call it as needed, but each one will perform it's role differently as
required by the customer.

Question 2: did the first question make sense?

Thanks
Tony
