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.

Need PDF with Digital Signature?

I was surprised to learn that there is no internal functionality to digitally sign a PDF file rendered by Cognos. I would expect that this would be a necessity for most Banks or financial institutions. After a quick bit of research (and some Google searches) I came up with one out-of-the-box method which might facilitate. The method in theory goes like:

Step 1: have the burst report run and save the output to filesystem in PDF format. Step 2: use a 3rd party software to process (digitally sign) the output file.

For step 2 I found something called "iText" (http://www.lowagie.com/iText/) which uses a Java JDK to post-process and add the digital signature to a PDF file.

I plan on investigating this method further but I'm interested in feedback or additional insight.
