All the embedded TCP/IP stuff I've seen advertised is based on PC/104
     boards, which are basically a single-board PC or peripheral with
     clearly defined physical dimensions and connectors, and ROM DOS. With
     a PC/104 board and a suitable PC/104 ethernet card you can use
     standard PC TCP/IP software.

     The TCP/IP protocol has many layers before it gets down to the actual
     ethernet hardware, and implementing this with an MCU would be onerous
     at best. PC/104 isn't cheap, but what is your time worth?

Hello,

the cheapest solution is finding a PC, adding a cheap Ethernet card and connect
that serial to the PIC. Then get a TCP/IP stack...
You'll be in business for about $100.
But maybe this is not what you are looking for, a bit bulky ...
