certificates

Hi All,

For those of you out there that use, or plan to use, Quiz module....

I'm trying to organize requirements for a new module that would work with quiz to provide certificates (PDF or otherwise) to signify the completion of a Quiz. These could be printed, emailed, etc. I have the current specs typed up in the following google doc:
http://docs.google.com/View?id=dvc73g9_6cpvkbpdb

And this has been discussed already some over on d.o in this thread:
http://drupal.org/node/501874

There appears to be a fair amount of interest in this functionality, so I wanted to open the floor for comments here as well, before firing off development on this. Let me know what you think... missing requirements? missing use cases? bad approaches? etc...

And... my apologies for the made up username here. My normal account isn't working... despite synch requests...
