Well, like I said, you *should* be able to just put an IAFileUpload in
your form, bound to a variable and that variable will contain the IAFile
object when the form is submitted.

Downloads can be accomplished by subclassing IADynamicResource. See
IAFormResource for an example that returns an image. You just need to
subclass IADynamicResource and define a #mimeDocument method.
You could do something like:
^ MIMEObject contentType: 'text/plain' content: 'This is a test'
So now if you do:
self callPage: IAMyDynamicResourceSubclass new
the user would be prompted to download a text file. Actually, in this
case the browser would probably just display it since it is 'text/plain'
hopefully that gets the idea across.
