I had a team member explain the project vastly differently to me. Can you provide a link that LE is only for personal/casual use? As a webhost we have offered SSL certificates to customers for ages. Unless it's free you will see very little uptake. Which eliminates the main purpose for LE to exist, from what I was told. I also have a rather compelling use case for far more than 20 subdomain certificates a week, but there is absolutely no "market" for that use-case - it simply increases Internet security. Which was the entire stated goal of the project, I thought. First I've heard that LE is only for personal use :)
