DemoPad.com

I now have an iPad mounted in the Kitchen and I am setting up Demopad to act as a control/message/weather center etc.
One thing I need to do is have web views update at regular intervals.
What is the best/most efficient way to achieve this.

Also any ideas for adding functionality to this setup would be appreciated.
Already have my security cameras working with it.....

If you use a label, and link the label to the webview, then setting the label equal to a value (even if it is the same as it was) will refresh the web view. So you can have a repeating page load action which sets the label every x seconds
