It's working great in several projects.  It now includes a generic network
packet send/receive interface, ARP incoming and outgoing, ICMP PING
response, IP, TCP, UDP, and DHCP.  There are MAC layer implementations
available for the ENC28J60, the ethernet controller built into some 18F
PICs, and the ZeroG WiFi module.

It also comes with a pretty cool (even if I say so myself) configuration
file.  The template is QQQ_NETWORK.INS.ASPIC.  You copy this into your
application and customize it to configure the network stack for your
project.  A bunch of preprocessor logic then figures out the dependecies an=
d
sets variables to indicate what is to be included.

I understand.  I didn't start out wanting to write a network stack, but it
became a necessity.

Yes, except for very minor restrictions.  See the copyright at the top of
each module.

All the network stack source code modules should be included in the PIC
development tools release at http://www.embedinc.com/pic/dload.htm.  Of
course it also should be in the Host Source Code and Everything release,
along with lots trees that may obscure the forest.

Take a look at files NET_xxx.INS.ASPIC and QQQ_NET_xxx.ASPIC in the SOURCE =

To use this network stack, you pretty much have to use my PIC development
setup including the preprocessor.  Of course that's a good idea anyway.
