Can anyone recommend any libraries/utilities they use to assist in distributing iOS adhoc/enterprise applications over the air, so users can install without needing a PC/iTunes?
There's a few hosted services around (eg. https://testflightapp.com/ - though that is not free for enterprise apps), but I'm sure in the past I saw a non-hosted service (ie. something I could install on my own server) and came with a client side library that was easy to hook into the app to notify the user when updates were available and allow them to easily install them. Unfortunately it seems I didn't bookmark it and a bunch of googling and searching on stack overflow hasn't found it.
I finally found the one I believe I was thinking of when I wrote the question, it's called "Hockey":
