Alright, here's an odd question - I've used a data view web part
linked to a column on an Agenda list that generates a full URL path to
a document that I'd like included on a page. However, from what I can
tell, I apparently don't have the ability to code in server side
include directives (it strips out HTML comments), and I can't use the
XSL include directives because SharePoint doesn't allow them.

Is there a way to actually include page content? I'm trying to
display the contents of a Wiki page library rolled up into a single
page. RSS would work perfectly, except for the minor fact that we're
set up with NTLM authentication, and thus RSS feed reader web parts
are useless.
