A thing of beauty!! It worked flawlessly for me, from opening the channel, to doing the instant micropayments, to closing the channel. I also appreciated that it kept track of transactions so when I viewed an article a second time there was no charge. The only tiny suggestion I would make would be a space between the number and the i, or to make sure the i shows up as lowercase (I thought I did not have enough in my test account of 400i because the “Pay 50i” looked like “Pay 501”). In a real-world scenario you may want to put it in fiat as well so someone understands just how little they are paying.
