Viewing burst versions - not just for your admin

Something that I've recently discovered in Cognos 8.4 (which was probably there all along): the "owner" of a given report can also see all the burst versions, even if they aren't set as the administrator.

So what about the recipient? Bursting, keys and the accessibility of the bursts in Cognos has always been a bit of a grey area for me. So, who gets to see what? In a graphical format, the burst output is accessible as:

Burst Key Recipient
Key1 Recipient A
Super Reader
Key2 Recipient B
Super Reader
Key3 Recipient C
Super Reader

If I log in as "Recipient A" then I will have access to output for Key1. If I log in as an account with membership to "Super Reader" then I will have access to Key1, Key2, and Key3.

Obviously a user with administrator rights would have sufficient access to view all keys for any given burst.
