Right, +1 for Tidy and DOM, it's the "real" way to do it. You won't
need to do it on every request -- you can either store the summary
itself as a separate text field, or store the length of the summary as
an integer.

This is crying out for a web service: The Excerpter. POST markup, get
the first X display characters back as a response, with embedded HTML
intact.
