Having been inspired by the above post, I downloaded VNC 3.3.3R2 which is 
the first version that supported the inetd option described above.  It 
took me literally two minutes (ignoring typo's) to update /etc/services 
and /etc/inetd.conf, and -HUP the inetd deamon.

Now I have X access from Win95 Pc's giving the XDM logon.  It performs as 
well as my Starnet X-Win32 and if it carries on this well, I'll roll it 
out fuller.

Once change I made to the instructions was to put '-query linux' instead 
of 'broadcast'.
