Don't know if GTC already have this concept, but
we could implement this and other culling algorithms
using custom graph travesers, like SGI's Performer.
This would allow great modularity. 

We could have basic travesers (like update, frustrum_cull,
visi_cull, render, network, etc) that would acept a 
[root] node* as parameter and do the apropriate action 
with the child graph.

This way we could have independent travesers and lot of
space for user custom made travesers.
