Hi Harald, Have a look at the ScheduleInfo element - http://read.cs.ucla.edu/click/elements/scheduleinfo . You should be able to prioritize FromDevice over ToDevice. Although I have never tested ScheduleInfo in userlevel Click I believe it should work.
Alternative you can also give Click's userlevel multithreading a go. Using the StaticThreadSched element you can schedule FromDevice and ToDevice on separate dedicated threads.
