Hi Steve,

first of all thank you for your feedback. It is very important for me,
to get a critical view on my ideas.

Of course, you are right. I only looked at non-interactive modules.

I tend to differ. The information I pass will not be mandatory. In the
meantime I found another module, which also uses the conversation
function to gather more information about the application
(Huderos-Project, but it seems to be dead).

Do you agree with me, that a module, that uses additional information if
it exists (e.g. by calling the conversation function and "ignoring"
empty results) is still "pluggable"?
