[Haskell-cafe] Scaling Haskell/Yesod on OpenShift

I was wondering, does anyone have experience with using Haskell/Yesod on the OpenShift PaaS? I've seen the Haskell and Yesod cartridges, but I'm wondering if there's any way to get Haskell playing nice with their load-balancing and automatic scaling capabilities? Would CloudHaskell be useful at all in this? I'm reasonably experienced with Haskell but very new to Cloud computing and Web stuff, so any advice, even if basic, is helpful. Thanks!
