Yeah that was my idea ... but I realized it's not going to work that way :(

... because Fluid lets you write custom code in ViewHelpers, not in 
nodes. But at the time of parsing, there are no ViewHelpers yet, so 
there is no way of calling your code. That means that if the 
"Node/ViewHelper generation" code is placed in the ViewHelper, it can 
only be called during the rendering process (that's what I tried first) 
... at least that's what I gathered so far, please correct me if I'm 
wrong ;)

Anyone ideas what else could work?
