I'm glad you got this working! I opened an issue with your demo, as the command in the README didn't work for me (so hopefully that will make it easier for other people to try this out).
I would love to promote this more widely to the Errai community. Would you be interesting in writing a post for our blog?
I would be happy to write a post if you can give me some basic guidance as to your expectations on content, length, format etc...
