If you wait until the end of the week, you'll be able to use the
object management API in 3.1 to do this.   I don't have immediate
plans to implement anything for the client myself, but you could use
the existing framework rather than rolling your own.

You might want to call state_bound() instead.   State_init will
deconfigure your interface and start over...
