What I have not seen is more shopping cart interfaces for cryptocurrencies and that is something that merchants definitely need because so far you can only really do it through payment processors which can obviously get taken down and so on, I would love to see a real standalone script that you can just upload to your site without have to rely on any third party APIs from exchanges and such just enter in the product price in Bitcoin and then upload your file.
Already possible. Just run bitcoin-qt on another server.
