Well…, we have a significant amount of spare capacity. And we like to pay the bills. Selling that spare capacity certainly makes paying the bills easier. We also have a couple of side projects (such as a novel crypto algorithm and an android project) that we work on as funds become available. We also develop unique engineering solutions to lots of different software and hardware problems and network architectures on the BlinkinBlox network. And we bang on cloud orchestration and file system fiddledybits too. And sometimes this is our test bed for those sorts of things as well.
And since we’re doing it all day anyway, why not share? Besides, allowing others to utilize our network resources provides us with a good operational context for ongoing staff development and a high-quality source of network entropy for some crypto-testing. We like to think of it as a win/win scenario for everyone.
