Check out some of the work we have done. Shared Mosaic is being built
to create a peer-to-peer environment for "real-time" information access.
Some documentation is available at,

Right now it is human driven on remote site, but the architecture is
not tied to this specific metaphor.

Is the project done ? No not yet !
Are we still working on this ? Yes ! and will be finishing real soon now
