So what's the long term plan? If tests require a bunch of ram, scaling costs seem at odds with "Free Forever". Will you eventually have a pay walled tier? Or will you seek donations to pay for infrastructure or...

I like the idea of a community FOSS or source available offering, I have a lovely pile of ram from the before times (when it didn't cost an arm and a leg).

I have way more than 20GB of RAM. Can I run it in my computer? And why do I need jude0? If I had a suite of tests, I could just run code against them. Just like Exercism.
