I don't understand what 'registered with RendererControl'
means? What method are you invoking to register?

VisAD has built-in support collaboration between remote
Displays, as described at:

  http://icecube.wisc.edu/~dglo/visad-collab/index.html

The IDV supports remote collaboration using VisAD but
without VisAD's built-in support. Perhaps someone from
Unidata can describe how that works.

Note there are complex synchronization problems with
remote collaboration, so if you can use the built-in
support or copy the IDV approach, it will make life
easier.

Good luck,
Bill
p.s., happy new year everyone
