[web-devel] Mongo for Yesod?

I hear rumor of a persistent-mongo. I've found http://hpaste.org/fastcgi/hpaste.fcgi/view?id=25669 but is there a more current version? I helped build the haskell mongodb driver which became the official one, so I know a few things about it. Also, I have some data structures to store for my website and would really prefer not to put them into a relational database. If there is a more current version of the code, could I take a crack at polishing it up?
