The Kitchen Safe : chastity and further ideas

I’m pretty sure you’ve all seen it while it was in crowfunding time, but in case you don’t know, the Kitchen Safe (http://www.thekitchensafe.com) is available for real, and it works exactly as they say : I own one since 3 months now.

I guess it’s ideal both for self or monitored chastity, drop your keys there (10 days maximum) and face the deal : break it for emergencies or give up any hope to get the keys.
There's no way to get back the keys until the set time ( for safety, always have a couple of batteries ready because if they're dead it sill won't open).
The cost is both ok ($50) and expensive enough to make you think about cheating it.

Beside chastity keys, I’ve been wondering how it could be used for live-style denial and remote management, here are some ideas blurring my mind and I’d love to here other possibilities:
- self bondage to a spot : like a chain going around the toilets bowl for instance. Or at contrary lock your bathroom and having to release in unusual ways…
- home prison : lock your doorkeys inside it and be prisoner (yes it’s safe, if there’s emergency, break the box)
- computer denial : put your mouse inside it – they’ve thought about it, it’s shown on the package box ? , along with playstation joystick.
- On the same line : internet denial : lock the LAN cable or the power unit of your IAP box.
- cigarette restriction : you can only smoke 5 during the whole weekend (of course, this also need home-prison , or you’ll go buy some)
- light restriction : lock your light bulbs in it : let’s live with candles !

What other devious ideas would you think about to make yourself or your online slave under restriction ?
