AFAIK both X 4.x and X 3.x support the same X protocol. You can start clients that connect to both version and also other version of X servers, for example commercially available ones, vncserver, servers running on different OSs (probably all Unix and unix-like, ms win (provided you have x server running there)) etc... of course, the client needs the xlib and maybe some other libs, you probably need specific version of those - if a client was compiled with a need for specific version of shared xlib (and other x libraries) then you need those. but that's not really X server issue. erik
