We've been using JWTs for our single-sign-on integrations (and some other tokens) with Livefyre customers for a couple years now. No downsides at all! Customers that aren't familiar with JWT are easily able to create tokens with all the libraries available in nearly every language. It's been depended on in some other lovely protocols like OpenID Connect. Great standard.
