Impressive work!

If today, I wanted to build an HTML5/JS/REST app, say something like
Globaleaks or Crypto.cat, that had note-Tor built into it, that should
work fairly easily then? Both of these apps make single JSON-type HTTP
connections to a single server, so the need for general purpose
web-browsing is not necessary.

Yes, agreed, and on mobile devices the option for proxying seems to be
never there by default, at least as part of the browser app.

The issue will be (and I am sure there are many more) that when your
Gecko/WebView container loads up the page you request, all subsequent
requests for content for embedded images, js, etc will also need to be
routed over this new API, and all standard HTTP connections blocked.

It is pretty exciting to see that Tor now has viable implementations in
C, Java and Javascript.
