Hey Peter, XEP-4 defines a few field types. I think that we should create a new field type for media objects so that clients could render it appropriately.
I like the media element that you included in the data form. I think that servers may choose to include the image itself in the form field or provide a URI to get it. I think I would expect the completed form to include a reply to the media field. In this case it would include the CAPTCHA value. Another choice, would be to just use the media field as a read-only field and then have another text field where the user could enter his CAPTCHA value. Am I missing something here?

CAPTCHAs and other computational puzzles in account registration forms: http://www.xmpp.org/extensions/xep-0158.html But for that we need to figure out how to include media objects in data forms. One proposal is XEP-0221: http://www.xmpp.org/extensions/xep-0221.html However, in the last XMPP Council meeting Ralph Meijer raised some concerns about including media directly in forms: http://mail.jabber.org/pipermail/standards/2008-May/018686.html I tend to agree with Ralph, but we need to figure this out soon. So let's discuss. :) Peter -- Peter Saint-Andre https://stpeter.im/
