Hello,
I am the author of the stack over flow question and can help out with testing. To be
honest I am very new to Mongo DB and NoSQL db's in general but I am willing to learn
and help code if necessary.
Here is another recent question about this implementation with a comment, so I know there
is a need for it out there.

Let me know how I can help.
Thanks,
Jimmy
