David,

    I had an atmel apps engineer tell me to look elsewhere for a solution.
He recommended www.ethernut.de and www.edtp.com both of which seem to be
pretty good starting platforms.  I've used the packet whacker from edtp with
a Mega128 & it worked although I've got a few bugs to work out.  I think it
was a good starting platform along with the book.  I laid out a board to
accept the packet whacker (if you go this route, make sure you get the
correct whacker version pinouts first) and within a day I was pinging and
UDPing with no rtos and no tcp/ip stack.  Total pkg cost for book and packet
whacker module was around 100USD.  They are to be coming out with a demo
board with a CF 802.11b card and Mega128 very soon.

hth,

Tony Vandiver

btw, thanks to the aforementioned Brian H. for the help.
