Hi, When you create a switch node switch([ (p1,s1), (p2,s2), ... ]) all the sources and predicates have to be evaluated as well, to give the switch function what it expects, namely a list of functions and sources. For example in your script, you have an item (check_blank, play_blank()), when it gets evaluated, the function check_blank evaluates to itself but evaluating play_blank() is done by calling the function play_blank().
A simpler way to say it is that the predicate function is called everytime a new source may be selected, but the source creation function is called only once, then the resulting source is kept forever. But with the first explanation I want to insist that there is no black magic about what is evaluated once and what is evaluated many times: it all comes from what objects are. If you pass a function to switch, it may call that function several times. If you pass a source, it doesn't know whether that source was built directly or using some function, so there's no way for it to call that function again. I hope this clarifies things. Now I must confess that I didn't read carefully all your script (I'm quickly writing this before heading out to work) so I'm not sure of what you're trying to do, but there's a good chance that you'll be able to do it without requiring human intervention through telnet.
