great work with dex guys! I remember talking to some of you back a year ago for using Auth0 internally for your products but you had some special requirements and it didn't work out. We are using CoreOS extensibly on our product for code sandboxing (https://medium.com/aws-activate-startup-blog/sandboxing-code-in-the-era-of-containers-294edb3a674) and we love it.
Since you are listing similar software, I thought adding Auth0 would make sense, here. Writing a post on our blog about chaining dex with Auth0 would be nice as well.
