Since you are comparing this option with an AJAX-based form, I assume 
you mean a technically simple form (just HTML, CSS, possible some 
client-side JavaScript checks). I don't see why such a form would 
only have fields name, organization, e-mail address and file upload. 
More specifically, why would we ask submitters to create and upload 
TCDL? Why can't we have form fields for each of our metadata fields, 
have a server-side script check the data, generate TCDL from this and 
send the TCDL and the content files to the list?

Is anybody willing to evaluate the accessibility of the interface?
I think the style sheet needs to be adapted because the background of 
the tabs ("Submitter Information", "Formal Metadata", ...) looks bad 
when you zoom the page. Colour contrast of the active tab may also be an issue.
