Yeah, I had good fun building a Polymer frontend for my weekend project, Secureshare. I got around some of the data binding shortfalls with polymer-signals.

It's been probably 2 years since I did it, so I'm sure there are better solutions - but I liked it as a dev environment. It's somewhat opaque, though.
