I've added you as previous commiters to the project, but feel free to leave/let me know if you're no longer interested.
I mostly wanted to gauge who else is around so that we could coordinate, but if it's just me then I'll go nuts on my own :)
I've been playing around with vagrant, trying to build a box that can run codeception tests (including using phantomjs with site5/phantoman) and I'm working on getting everything controllable via webception, so in theory, you'll be able to configure the box to point to your 'sites/' or 'projects/' directory, and run tests against them all locally (via vagrant) and it'll all be platform-independent and such
I'm just figuring out the best way to handle the extensions/different versions of codeception within the projects VS webception's version
