Thanks to Eric Kidd, I've got Fargo Publisher working on Heroku.
If you want to give it a try, this is what you can do:
Choose Settings from the System menu.
Click on the CMS panel.
In the Server field, enter: fargopublisher.herokuapp.com
Here's a screen shot.
You should be able to edit named outlines, give names to outlines.
Verify that the changes make it to your beta.fargo.io site.
I just created a repository on GitHub with all the built-in Fargo 2 templates.
When I update a template, as before, the change will be reflected in the globals outline, but now it will also update the repository.
You are free to fork them, modify the result and redistribute.
I licensed them under the GPL, which means any modifications you make have to also be released under the GPL. Read the license for the specifics.
