Andy,
   ip ospf demand circuit is correct. You only need to configure it on
one side. The most common reason I've seen for it not to work is when
people are doing redistribution into ospf and they don't realize that when
the link drops it's going to advertise that fact, which is then
redistributed into opsf and the link is brought back up... ;-) If that's
the situation, try passive-interface and/or a distribute-list. Another
important thing to remember is the neighbors need to come up one time in
"full" state for ip ospf demand circuit to work after that.
