Having stumbled across a few comments with links to various projects on github attempting electron replacements, it seems that the project NodeKit is a bit more advanced and has elements that are somewhat still active. Maybe some coders here would be interested in helping out. The url: http://nodekit.io/ The repos: https://github.com/nodekit-io
No, I am not affiliated in an way. I did notice that the main dev was keen for pull requests.
Like a few previous projects, it uses the native browser where possible. The difference is that it's also bundling modified (but code compatible) node library (if you want it).
There's still a bit of work to do on it, especially the equivalent electron-packager style bundling, but I thought it relevant here.
