Well, I checked out the survey builder module from AD CVS, played around with it, found it too difficult to use for our client and implemented branching for the simple survey 😉. Its not ready to be released [user dokumentation missing...] (and anyway only working within ACES aka. 3.4.5 and higher), but if someone is interested (e.g. because he wants to port survsimp to OACS4) I'll gladly share our code.
