    Hello, I can speak only for Ethernut which is a great design, and open
source,
software and hardware. Ethernut boards are available at Egnite but you can
build a clone without ethernet parts, reducing component parts to only a
mega128, 32K SRAM, HC573 and a RS232 driver. The implemented TCP/IP
stack has some high level protocols implemented however no SMTP and POP3
but these are quite easy to write. PPP works very well on fixed line modems,
GSM GPRS and CDMA.
    A big bonus is NutOS, a threaded cooperative OS.

Cosmin Buhu
