James,

Thanks for your soon reply!

I think that your answer is a good approach, but I would like to
pass/modify the module parameters while this one is running. I believe
this way allows to the user more flexibility to add/configure the
module behavior.

Please, let me know if you have any idea.

Thanks again.

ivan.
