At the very low end, you can hook a PIC to a MAC/PHY chip.  Microchip
supplies a TCP/IP stack for both 16 and 18 family if I remember right.
Since PICs don't have DMA, the data rate probably isn't that high and there
will be significant software overhead just moving the packets around.

Dallas came out with a new chip about a year ago that comes with a complete
TCP/IP stack in ROM.  It's uses the 8051 architecture.  Unfortunately it
requires external memory for the user program.
