That looks really useful, although the phy doesn't appear to have 
auto-MDIX functionality, which the Luminary devices claim to support.

As usual with Microchip, 40 MHz clock=10 MIPS. Plus, it's an 8 bit device;
it doesn't look like it can handle much data. Anyway, thanks for the hint!
I didn't know that some PIC had the ethernet interface.

Yes, even Mouser and Digikey have them in stock (as well as the low-cost
development kit).

Looks interesting, thanks! I was hoping that my message would have started
a "my processor is better than yours" thread, it's in this way that you
learn the most. ;-)

Last time I checked no development tools were available for Linux to
compile the Microchip TCP/IP stack. Is that still the case?

Microchip's tools are based on gcc, you could easily recompile them
for Linux.  The sources are available on their web site.

I don't know if you can program the chips from linux yet, but they do
document the protocol needed.
