Great! I'm very interested in this, I've also got an app which I'll
need to port to python3 at some time.

Looking at the branch, it seems that this is basically going to be a
re-write of the existing code. You're planning to keep the mechanize
backend available?

Might I suggest zope.testbrowser.webtest for the WebTest backed
testbrowser rather than zope.testbrowser.browser2?  Could you also keep
the tests for the mechanize testbrowser intact? They could be skipped if
mechanize is not importable and mechanize downgraded to an optional
dependency.
