Partially.  I've been thinking about having an {$Excerpt} page 
variable which provides an excerpt of an page -- i.e., it gives
the page description if one exists, or the first few paragraphs,
or the words surrounding any search terms if entered.

I've been thinking that {$Excerpt} should just return plain text
w/o any markups.

IIRC, it is possible to set $FeedFmt to call a function -- i.e.,

    $FeedFmt['rss']['item']['content'] = 'MyContent';

which then calls the MyContent() function to determine what
should be generated for the <content> tag.  This function could
then grab the page markup source, convert it to HTML, etc.
