I don´t know exactly what will happen with the AMP project.In the AMP 
home page they are saying that will disable the machines and collection.
But the AMPlet code is available and can be installed in other machines 
and networks. That´s what we did here in RNP.
The amplet code is disponibilized here: http://amp.nlanr.net/Software/AMP/
