I'm excited. Today was the first time I tried Sandstorm via their demo serivce, and I must say that I am genuinely surprised and impressed with the level of polish. One click gave me a private gitlab, a collaborative document editor, and even a running instance of browserquest!
This level of polish might just be what it takes to get the masses to host their own digital services. I'm strongly considering setting a sandstorm server up for my family.
One question promptly and prominently pops to mind: Given the focus on non-technical users, How does sandstorm mitigate issues that are caused by NAT and NAT traversal?
