There is a function called "Interface" at hierarchy and content containers.
http://www.ventuz.com/support/help/V4_0 ... Interfaces
If Interfacing is selected you can copy-paste the content of one container into another
Everything in the 2nd container is changed except for exposed values
With this in combination with the container Info (name + Index) helbs you to get some kind of instance.
Say you want do a coverflow.
You use a DIR node to get all the cover-images from one Folder
now you make as many hierarchy containers as the maximum amount of images could be with an index from 00 to max.
Now in each container you expose the input of an array indexer and link the "index start" to the name index of the container info node and connect the output of this indexer to the texture loader
Then you copy the Container and paste it with ctrl+shift +v or (paste container content menu button) into every other container
now connect the result array from the DIR node to every exposed "array" container input.
Now each container loads a different image.
now hen you change something in one of the containers (like adding a translation based on the name index, or blocking the container if there are less images then containers (container id<Count from DIR)) you just have to paste it again on all other containers and all connections stay alive
There are a few negative sides of this:
the number of these Containers is not dynamic if there are more images then containers only the first images will be displayed.
If you have a lot of containers you soon have a jungle of connections
All containers have to be validated if any input changes
I hope I could help a bit..
