 I'm stuck with shared internet resources on a boat and I need to pay someone in BTC.

Let's say I have a private key worth in excess of the amount I need to pay. What is the most direct way I can do this?

 A lightweight client like Electrum is an option for me since I do have the ability to run an executable. However, I don't like trusting machines that can run executables without 2 factor authentication like one time use passwords. In addition, it would be nice to be prepared for the time when running .exe's is not possible.

I also don't trust fully online hosted wallets now after MyBitcoin, MtGox and the others.

 I think there's a case for being able to store part of a wallet locally, and/or with one time passwords, and part remotely.

This can be done with a little customised hacking and the paper based javascript wallet system but it's clunky for this application. The main problem is that even if you prepare a load of private keys on a secure connection you then can't divide those amounts offline or online in a secure way without that trusted computer.

you can import the private key into blockchain, and setup 2 factor auth.

Thanks buddy! Didn't know Blockchain.info had that!

I guess the other way would be something in javascript like paper wallet but able to do transactions

You can even use blockchain.info offline while your wallet is decrypted and you're creating the transaction.
