How to add website visitors to a pool? As an experiment, I will have website visitors mine litecoins. Yes, I know this won't work very well, but I simply want to try it. If I want the visitors to be part of a pool, how should I create user accounts for them? Is it ok if I have them all mine under the same worker name, or do I have to create individual workers?
This kinda thing gets your website put in blacklists.

The only way (I know of at least) to mine in the browser is Bitcoin Plus, which actually is just a wrapper around a background Java applet. So you would probably want to make a Java miner and then work off that.
