Impressive climbing, again!
It should be at least possible to try out a 11-34 cassette (or does that Dahon have a freewheel?) with existing derailer just to see if it would work - it may. If not, there is an alternative hanger for that Model which takes a conventional derailer. thorusa would have these, and would be able to give expert advice. He also sells 9sp wheels for a great price.
