Maybe I'm accidentally mixing terms...  I assume (which is probably
incorrect) that IPsec == 802.1X.

What I'm seeing is that on the "Properties" for the connection there is an
"Authentication" tab.  That tab has a check box to enable 802.1X and allows
you to select an EAP type.  The default is "Smart Card or other Certificate"
but there are other choices "MD5 Challenge" and PEAP.  There is a button to
configure advanced options which include setting where the certificate come
from (smart card or certificate on this computer), setting "Trusted Root
Certificates", ect.

Using "gpedit.msc" I did see you can set IPsec to a "pre-shared secret" but
that only covers authentication with the network not encryption.  The
problem is that the machines that I have to work with are XP Home machines
which, if I remember correctly, doesn't have this file.

Hopefully this answers your last questions:  I want to encrypt all the data
between 3 machines (currently 3 maybe more soon).  I have been informed from
several places that WEP is not enough because of some fundamental flaws in
the protocol (which may not be solved with WPA).  I need the process of
encrypting the transported data to be as transparent as possible because the
reciepients of this system are not "tech savvy".  The given budget
constraints (or more appropriatley the lack of any funds) the WAP is
produced by Linksys ( BEFW11S4), which I don't believe is capable of being
an IPsec endpoint.
