FYI, you don't need the enterprise account to wirelessly distribute apps any more. You can do it from within XCode using a standard developer account - once you've built and archived an app you can pop into the XCode Organizer, select the version you want to distribute from the archived apps section, and click "Share". You can then build an IPA and .plist for hosting online, and for download by provisioned devices.
This is how we distribute all our own apps to clients for testing, it saves on a lot of troubleshooting! We have it all hooked up to our CI system too, as you're intending to do.
