There's a fair amount of risk in everything: Do you trust the admins of you hosting provider? Are you sure about the source code or binaries for all the pieces of your runtime stack? Did you audit every piece of your own source code for security issues?

But right now I'm not asking people to drop everything and use rayburst to set up their production servers no questions asked. Just to try it out and see if it does what they need.

If someone then decides to use it for production setup, we can talk about how to guarantee security and stability in the configuration for their setup. BTW this is why you enter into contracts, pay for services, etc.
