Ruby OS with UI in browser

Hello,

What you think about open source OS which managed in browser?

This gem in demo of make UI for ‘top’ -
Scout Realtime by Scoutapp.

I image in OS two parts:

  1. Infrastructure to run browser
  2. Infrastructure to run web server

OS benefits, could be:

  1. Easy to develop UI application - just web app
  2. Headless backward computability, UI app depend only on web server API
