I confess I haven't dug into the code yet....
How hard would it be to add an additional resource type? It would be based on plain text, but when the text is displayed it would be run through a custom formatter.
Its just to get an idea how deep in the code these sort of features are before I take on something that a might regret!
Thanks!
It should be quite easy ... see mod/resource/view.php and the list of types in mod/resource/lib.php
