Power Saving for the WiFi shield

As directed by the WiFi library reference page, I am posting my request/suggestion here.

It would be really nice if we had the ability to control power state of the WiFi shield programatically. I am realizing that any power saving features that I may implement in my arduino code may be rendered irrelevant due to the fact that I can't control the power state of the WiFi shield.

Just a hope. Thanks in advance. The Arduino WiFi shield has already been 100% simpler than others we have tried.
