ArcadEd - I'm not exactly sure what the process is, but if you could state what accounts one needs to create, then they just give you the package from cocoon or whatever they use along with appStore descriptions, then you use their account with a temporary password to submit the game. Then notify them when/if it's approved and they can change their password back to something else and everyone's happy.
You could work out some additional details maybe, like if $10 per test on a device, fee for successful application, reduced fee for failed etc. Since I haven't been through it before I don't know the specifics, but I haven't been through it because it's such a massive pain compared to Android.
