Module not working :(

I'm setting up a test environment for all the various SoC projects in preparation for the talk during Brussels.

While I can login on two different browser sessions pointing at localhost, and each user will see the fieldset updating as they make changes, the two users don't see one anothers' changes.

http://ernestdelgado.com/drupal is down, so I can't use the test site there to show it off. :(

Any help??
