My first impression is that if we have dynamic routing,
i.e. we can route to nodes passed as fields
or events, we can do part of what Balaguer does.
His connector objects are similar to connection
classes in VRML++. But constraints can propagate
values in either way, while routes only one-way
connections.

There are interesting other features in the
constraint language, namely the path expressions:

e.g. SUPER.children.children.material
or myInputEvent.children.children.material

But they also allow functions as part of a path
expression, e.g. the function "or":

myInputEvent.children.children.material.or(diffuseColor,specularColor)
