This directory contains code nearly identical to that found
in CH7/SSND. The only difference is that PIPESEC.CPP, which
replaces SSNPRECV.CPP, contains security code that allows only the 
guest account on the local machine to access the pipe. Run PIPESEC
on your machine. Run the sender in a different window on the same 
machine and the two programs should connect if you are logged in
as under the Guest account. Under any other account you should get 
an access denied error. Try other accounts besides "guest" in the 
code.
