As the author of that blog post I can confirm some of that is out of date. Hopefully I can find some time to update the post for 1.0, but the main concepts still work.
At Pivotal Toronto we're running iOS and Android builds using a mac mini as an external worker. What's been a great built in feature is using the pool resource to "check-out" a device and lock it from other tests while a suite is running.
Updates would be awesome but that blog post covered a lot, thanks! I'll spend some time looking into Concourse now.
Also, if you have some free time I would love to chat about your experience so far -- I work about 15 minutes away from Pivotal's Toronto office. My email address is listed in my profile.
