I'm part of a small group of friends who are iOS developers. We want to create a website where any one of us can upload their app and the rest of us can share it with our clients/acquaintances just to provide a feedback, before it hits the app store. We were planning to use ad hoc provisioning profile to achieve this. The problem is how to add device ids to the provisional profile without needing the original developer to re-download it from apple developer portal.
Note: We are willing to share our distribution certificate with each other
