Google searches the ODE mailing list really well if you put "site:q12.org"
in the search string.  I found that post with this query:

Of course, I had the added advantage of knowing who wrote that post, and
that made it a little easier to track down. :-)

I'm using ODE and Demeter in my project, they work pretty well together.  
However, I think I got the diagonals wrong in the code I'm using (and thus
in the sample code).  Like, Demeter turns squares into two triangles by
putting a diagonal edge, and I've got the diagonal going between the wrong
vertices.  At least I think that's the problem.... In sharp valleys it's
sometimes clear that what's rendered isn't quite what's being collided.  
Most of the time it works great though, so I've been able to put off
fixing this for a very long time. :-)
