2069 * client waits to *read* a byte.
2070 *
2071 * server creates a named pipe with a random name, sends a byte
2072 * contining its length, and its name.
2073 *
2074 * client reads the name, connects to it (using Win32 API).
2075 *
2076 * server waits for connection to the named pipe, then calls
2077 * ImpersonateNamedPipeClient(), notes its now-current credentials,
2078 * calls RevertToSelf(), closes its handles to the named pipe, and
2079 * is done. (Maybe there is some other way to get the SID of a named
2080 * pipe client without having to use impersonation?)
2081 *
2082 * client closes its handles and is done.
