I will implement your suggestion (not the newrelic hooking ;-)) Give me a bit of time, I'm working on tidying up ruote-dm (and ruote-sequel) as well as ruote-couch, plus bugs like http://groups.google.com/group/openwferu-users/browse_thread/thread/ee493bdf8d8cdb37 I also have to terminate the work with Raphael on the filters. Then it will be 2.2.0. Looking forward to your feedback.
