If you say STF> it's possible to install an instant messenger server, the answer is "it's a STF> waste of time and ressource". Maybe you don't know enough point to point chat applications (as I said there are hundreds, maybe thousands applications which do not require a server). Netmeeting _is_ point to point. And multiplatform (I mean, there are *nix clients). So is talk (and yes, there are quite a few talk clients for windows). And many, many, many other applications. STF> As to company policy, if you understand why there're companies STF> allowing PCAnywhere but forbidding Internet surfing or instant messenger, STF> you could also understand why they would forbid netmeeting but allows vnc. So let me get this straight: company policy forbids program X (ytalk for example, or any other simple chat program), but if you include the same code into VNC the same company policy will allow it, because it's called VNC.

I assume the "clear" choice for you is to use port 80 for VNC, isn't it ? Even if the company policy is "NO VNC". If it were "only VNC" they would open other ports, not port 80, isn't it ?

You say that if you have a VNC (or VNC + chat) with a security flaw then if the flaw is exploited you could see this on the screen. Why is that ?

You cannot have the whole list of features because you don't pay anybody to do it. Remember, the wish list is huge:chat, encryption, file transfer, remote registry edit, other windows related stuff (start/stop services, etc), remote shell, streaming the audio, etc. But all of these are not real problems; you can get around (sometimes in more than one way). I have no idea where are "the vnc people" going, but I assume the focus is on problems like "vnc crashes with windows X service pack Y", or "vnc is too slow even with a lot of bandwidth", because we cannot really solve this problems using a chat client, or ssh, or ftp server, or whatever other tool freely available. >> -----Message d'origine----- >> De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] >> EnvoyC) : mardi 18 fC)vrier 2003 20:22 >> C : '[EMAIL PROTECTED]' >> Objet : Re: Wish : chat between client and server >> >> >> There are thousands ways to chat between 2 computers.
