Cool ... Comments:
1) I don't see the widget container and ECMAScript engine. If we're using
HTML for display rendering, the architecture needs to include explicit
considerations for a few core technologies.
2) The use of D-Bus creates an internal communication model that is
different than the external. Seems like some creative API mapping could
make the two types of communication similar.
3) Why is there a browser on your server side picture?
