Use firmcoins.

They're there, in their room. Your mining rig is on fire, yet you're very calm.

Bad idea, whoever get their hand on the paper wallet is able to read the private key and steal the bitcoins. Send a transaction, no one can steal it

Use keyless paper bills.

Whoever can get their hands on your paper dollars can steal them! The point is not using the internet. I think we need bitcoin bills. 1BTC, .1 BTC, .01 BTC. If we had 1million BTC in physical bills in circulation, things would get interesting. Anyone got a printing press?

http://bitcoincard.org/ <---this project could help. I am concerned about the tracking abilities tho, but the video on the website says one can choose different IDs. If you can completely deactivate the device (no NFC!), as well as change the ID (not the User ID, but the ID of the device itself) or if there were no unique IDs, then this could be a really good solution.

Hard switch on the antenna would be nice

Envision a 3-D printed plastic coin that has the privkey printed inside it. The only way to get at it is to break the coin open.
It is techically feasible to design an open source 3D printer software that could be married to a custom bitcoin client. That way the privkey could be encrypted end-to-end, and the only way to know the privkey is to break open the printed coin.
The privkey would be printed on a vertical plane sandwiched closely between two other vertical planes. This way the privkey cannot be observed during the printing process.

I just registered for the $PLOTS presale! Thank you @plotsfinance for allowing me to purchase tokens at the discounted valuation of only $0.015 per token, a special offer for anyone who participated in the airdrop. Tier II round is for the public at $0.025 per token. Allocation is very limited and you need to register first using the official Part III link found on their twitter. Register using my referral code CPB5 to receive 2,500 points.

The trick is to prove that the privkey actually has value / has not been copied.

Which side doesn't have Internet ... the sender or the recipient (or both)? From another thread:

Won't work, as it loads the unspent outputs of the input addresses to generate a transaction to sign. Can you generate a 'spend all unspents' transaction without a list of input keys?

I like the idea of a handheld radio that can send a transaction (say over GMRS or MURS, but that might not be legal) to a receiver that would then send it over the Bitcoin network.
Sure, there wouldn't be a whole lot of use for it given the ubiquity of smart phones, but I like the idea of not depending (as much) on a mobile internet connection. Not to mention the device would be Bitcoin centric and therefore more secure.

Bonded/insured company for xxx value insurance per coin? Would an insurance company even touch it?

Printed keypair tokens are the ultimate anonymous transaction. No way to tell if the coins changed hands, or if they are accessible by anyone at all. Long strings of transactions could be completed with no paper trail at all, digital or otherwise.
