I have a tablet PC that I have framed and hung in the kitchen, mostly to replace an aging Sonos controller. Now I would like lock screen to display some useful things such as a detailed weather forecast graph. I do not know, however, how far one can push the "personalization" of the lock screen (from what I understand, not very far).

The best thing by far would be to force the lock screen to behave like a browser, pointing to a webpage that uses jQuery (or similar) to pull and update any content. Is there a way to do that? I suspect that the answer is "no", but it doesn't hurt to ask.
