Thanks Daniel, will have a look at it and will contact you with any questions I 
have.

Hello Sven and all Blender devs, @Sven: If I understand correctly, you are 
trying to implement a visual programming language? I don't know how much 
bibliography you have and if you need more but I thought I'd speak up a little 
bit : I work for the Openalea project which implements a dataflow visual 
programming interface that lets us build dataflows pretty much like the 
compositor in blender ( although not as good-looking in my opinion, we have a 
taste for cheesy colors :) ). On the business side (ie. not the GUI) the 
dataflow structure is seperated from the dataflow evaluation algorithm. There 
are a few of them though the main ones are the "lambda evaluation" and the 
"discrete time evaluation". Here are some references: An early presentation of 
the project :

(http://www.euroscipy.org/file/3707?vid=download, page 102) contains some more 
details on the algo. Have a look at their own references, you might find 
interesting articles for your project as Openalea started from what others had 
done in the visual programming domain and expand upon that. Greeting,Daniel
