It's nice to have a long term horizon of a hundred years of mining, and it's true that web-mining can achieve a higher decentralization than any other method. However, at the moment there is still one fundamental element which is totally centralized, and this is your website, where the people can mine. Should your server disappear, so would the network. And obviously your server cannot plan to be online for the next 100 years. How are you planning to solve this critical issue?
Yes, anyone can import our miner&wallet in their website only adding 2 code lines. But the safest place to mine WebDollar will be our website for avoid scam.
An external wallet client with built in pool hosting would be a great way to solve this. I am not too sure how difficult that would be, but it would be very beneficial.
