Just emitters in free space.

If you have the right routing protocol and interference control you can get a lot of parallelism and increase the effective bandwidth of the mesh.

Maybe, higher unemployment rate amongs engineers would help. <sigh> As long as the guys with the money and power want to squash what you are doing, you will eventually get squashed. Being on-the-run doesn't appeal to me much. I would rather find a way to get them to stop (or never start) chasing me. Brian Lloyd [EMAIL PROTECTED] +1.530.676.1113 - voice +1.360.838.9669 - fax
