Probably the easiest method would be an iframe.  Take the user's edited
template, save it as a temp file, use an iframe to make a separate call to
the server to get a rendered version, to be displayed via the iframe.  Give
the user a method on the containing page to accept/revise their edited
content.  If accepted, issue a request (either via regular post or via in
background with an ajax request) to move the temp file to its permanent
home.  Obviously if the edited template results in a fatal parse error or
something, the user will not "accept" the edit.

Iframes are generally irritating, but this is one case where it might be
worthwhile to 'em.
