This was a reason I made this project. Thank you for great feedback! :)
I'd experimented with embedding Javascript Bitcoin miners in my website as a means of monetization without ads. I see this as a more intuitive version of that which restricts the user based on usage (posting rate) instead of on viewership.
The issue I encountered was a miniscule rate of return on the JS-based mining. Do you think that if HashCash integrates with BitCoin for monetization/mining purposes, JS speed will be a limiting factor?
Right now there is no payouts to webmasters, but this is next feature I am working on. It will be made directly to webmaster dogecoin address from p2pool I am running for this project.
I've been trying to get Hamiyoca's JS miner to work with mupool without much success. (Stratum is straitforward. I'm just dumb.) p2pool is way easier from the cursory glance I've given it. I'm surprised I hadn't heard of it before.
Any chance I could trouble you for an invite for jo.jcat at gmail? I'm already using proof-of-work to keep spam off my blog (josephcatrambone.com), but I wouldn't mind switching early to something more conducive. Hell, if the payouts are nonzero when they roll around, I might be able to strip the ads. Alternatively, what's the official way to request an invite? Sign up for the news letter and wait?
I will definitely email invite codes to everyone once it is ready to go.
Have you done tests on many platforms to show which ones are supported?
I'd probably like it to be more automatic... a single clickable progress bar without the need for the 2 text fields or generate button.
But yeah... this is ace.
As for support on different platforms - Safari is tricky one right now. Trying to figure out why it is not working. IE before version 10 will not work, because it uses typed arrays in javascript. Other than that it should work in any modern browser in theory.
