Hi Len,

This concerns me greatly so I thought I'd just comment.

Good stuff!

If it complicates stuff I would be all for removing this requirement,
instead have a dedicated NIC. Laptops have wireless and potentially
having an additional NIC in a desktop should be low cost.

I see, so the "box" will be a dedicated computer. There would need to
be some custom hardware to wire in AD/DA?

8 or more is where it starts to get interesting, below that I think
USB suffices.

I'm guessing this is early days for this project, is there anything
you know you want help with?
