How about a complete product?

What do you mean by extend?  It is possible to edit the user folder
code, or to create a ZClass which subclasses it to modify the type of
object returned by validate().  IMAPAdapter does this, it's validate()
method actually works with a low level connection manager to return a
User object which defines a whole IMAP API and a connection logic
(including connection caching and automatic connection reconstruction).
Thus, IMAP operations happen from the perspective of AUTHENTICATED_USER,
like so:

    <dtml-var standard_html_header>
      <dtml-with AUTHENTICATED_USER>
        <dtml-tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1>
	    <img src=<!--#var icon>>
          <dtml-var shortname>
	    <dtml-if num>
	      (<dtml-var num>)
	    </dtml-if>
        </dtml-tree>
      </dtml-with>
    <dtml-var standard_html_footer>

imapFolderTree() is a method of the User object.
