Unfortunately, I like the Network Sensor concept (due to its generality), 
and don't forget:

* An X3D viewer is not required to support Java (either Internal in a  
Script node or external)
* An X3D viewer is required to support  ECMAScript in the Script node - if 
the viewer supports the Script node
*  An X3D viewer is not required to support external SAI with ECMAScript
(I copied these sentences from another forum, Author: Leonard Daly)

When I use network sensors, it's possible to implement rather complex MU 
animations/simulations just using ECMAScript, without being dependent on 
the SAI/EAI.
