as Graeme said, just call them all "sandbox"

i think it depends on its function. if the serial driver actually goes to
std{in,err,out}, then perhaps "serial/sandbox_stdio.c". let's not assume
we'll only ever have one pseudo driver that we can use under the sandbox :).

why not just build on top of tun/tap ? then we do get "real" network traffic,
and you dont have to write your own tftp server because you can simply use the
same exact one on your development machine that the board would connect to.
