Any Interest in a Chatter / Spring / App Engine Tutorial?

Following up on yesterday's post, Get Ready for VMForce - Here's How!, I was thinking about putting together a series of tutorials on building a Chatter app on App Engine using Spring MVC with JDO. This will take considerable effort and I'm just wondering if it would be valuable to the community.

Tell me what you think.

UPDATE: I spoke with Umit Yalcinalp at and they are planning some webinars on this topic the end of August. I don't want to steal their thunder so I'll possibly look at doing this mid-September sometime.
