I have developed an alternative secure mail system designed for easy of use (it does all the key generation and signing under the hood, it should be easier to deploy than standard SSL certificates and PGP signatures) You can find an alfa of it on http://resomail.com, the secure domain generation is not yet ready, but I thought that bitcoin crowd might be interested in an alternative secure mail system and I could sell domains for bitcoin and protect against bots by offering *.free domains for value of Bitcoin Faucet (now 0.001 bitcoin), there also will be not free domains like *.usa or *.can .
Before starting to implement this feature I need to know – would anyone purchase alternative domains for ResoMail?

Let's say that person A mined some bitcoins, so now all the payment fees for those bitcoins goes to him. Person B wants to buy from person A the right to receive those payment fees.
Is it possible to safely transfer "mined rights" from person A to person B?

How does it work?
From the wiki I've read that it will go to the miner who mined the coins you're transferring. What will happen if the miner is not online?
