+1 (forced)
Since sylvain already started to do the change for envire/viz.
Not using the vizkit namespace for visualizations did actually lead to 
some problems, since the ruby part seems to assume that all vizkit3d 
plugins are in the vizkit:: namespace. I've commited a small change from 
sylvain to vizkit to allow the registration of visualization using the 
full namespace.

cheers,

Jakob
