Shutting down publishing point after live broadcast

Hi,

Is it possible to shut down the publishing point after live broadcast is over?  This has to be done from outside of the server environment.

According to this post, http://blogs.iis.net/samzhang/archive/2010/11/01/live-smooth-streaming-publishing-point-advanced-settings.aspx, I should be able to shutdown the publishing point to idle state. 

Any suggestion?

Thanks.
