Yes, ANSYS, and CFD.

With regard to peerkeeper, this is my thought:
The cryptocurrency is the money of internet, and is the most suitable for content consumption/production on internet, there is a huge potential market of online payment for content.
e.g. BM's next product: steem, is a social media on blockchain with content consumption/production.

Many customers dislike to pay apple music monthly for 10$/month, they wanna pay each song they listen, when they don't listen, should be no fee at all. Many customers have to deposit s small amount of money via paypal on various website to download articles, attachment, etc, this is really tedious. I can imagine a bright future that every click of your mouse on webpage can be charged fee if necessary. Every information exchange, can be a money transaction. In this way, advertisements can be removed from websites and customers directly pay for the service. e.g. You pay 0.1$ to watch a video on youtube, and the author gets the 80% money while 20% belongs to website.
Peer keeper can be a browser plugin, a integrated wallet on chrome/firefox(open sourced), a customer deposits a small amount of PPC/BTC ( e.g 50$), and when browsing on internet, when clicking mouse, posting thread, downloading files, even viewing article, the payment is automatically finished within several seconds. Because the traditional payment such as VISA/MASTER(5000-50000tx/s) cannot handle such micropayment all over the world.
In this way, we can change the business model of existing millions of websites. Eliminate the agent/advertisement between customers and websites by blockchain technology!
Yes, PPC is not for micropayment, but when 3rd party payment service involved......Or thunder network with 1million tx per second comes out......
