with the 10 and 20 chip boards, will I be hooking up 1 USB per board? or will the boards daisy chain together to "talk" to the computer/internet?

Stacking will be similar to the cairnsmore boards from Enterpoint.
The CAN-Bus module connection will allow modules to form a big cluster like the Avalon machines.
That way you need only one USB-Connection for up to 16 Modules, maximum bus-length >10 Mtr.
