You may want to to consider implementing IPv6 if you want every device
around the world to have a "unique" IP address. :-) I don't think the Pic
you mentioned would cut running a TCP/IP stack. Most likely you're going
to want at least a few hundred KB of RAM and ROM to run this. Since
you're talking dumb devices, my guess is that you'd want to do something
like TCP/IP over PPP on serial link to the device.
It's probably cheaper in the long run to just get a TCP/IP stack running
under ELKS, and then buy 80x86 based SBCs.
Has there been any work on getting PPP support for ELKS?
