I have fiddled with the idea of such a device. A spec sheet is at
http://www.beyondlogic.org/etherip/SmartPenguin.pdf but beware that
it is totally vaporware. (Did someone mention a shortage of flash)
I have a a board 4 x 2.5" with 0.1" headers surounding it. This
allows daughter boards to be securaly stacked on top of the device.
Just an idea. See what you think.
