You could easily take Fennec and merge in the latest Torbutton alpha -
we did some basic tests and found that the hardest issue was that the UI
was mostly gone. However, if the entire thing was configured in the
"safe" way for Android, a lot of that wouldn't matter. If you did a
custom build of that - it would be pretty great - it would also be a
good start for adding in other stuff like HTTPS Everywhere.

That's a project that the Tor Project would really like to see get off
the ground but it's item ten thousand or so on our TODO list.

If you ship an entire browser, you can easily use a proxy like Tor that
ships in Orbot. You control the entire stack and that's a hell of an
awesome application.

All the best,
