Are there any hosts like this?

I'd like to find a good host, with the following:

1) Key back button, and side thumb button.

2) Ability to input code to allow powering (yeah, OCD safe), with #2, I guess #1 isn't required.

Because of the obvious danger of lasers, I want to make one that is absolutely foolproof (within reason), with regards to kids. What is the first thing kids do, when they pick up a flashlight? They shine it in their or someone else's eyes.

Yes, yes, I know you don't leave them laying around. But anyone who says they keep them under lock and key at all times, is probably lying. I do, but when I go take a pee, I don't lock it up. I do a quick disassembly but rarely lock mine up, if I run to the fridge or go take a dump. Only when I'm done for the day, or a long period, does it go into the safe. I don't have kids in the house but many people do.

A safe switch seems very reasonable. But do any currently exist, on hosts that we can buy? I haven't seen any.

If not, I might have to design one. I've even been thinking of putting an RFID on one so that it won't turn on, unless the RFID chip is near.
