why is tunneling X through firewalls noticeably safer then just doing packet filtering to allow it through? if the only answer is becouse it prevents someone from intercepting and tinkering with the TCP datastream then it's only relavent in some situations and you are saying that in others it's perfectly safe to just do packet filtering.
Perhaps, it's not about safety but rather manageability. It's a lot easier to manage that traffic if it's done as part of a single application rather than as a whole protocol suite and multiple ports. If I recall correctly, X11 is one of those protocols that tries to negotiate ports rather than just using a fixed few. This may be a bit of a hassle which may cause errors or having ports open that don't need to be. I know it's lame to use the 'it's easier this way' excuse rather than just doing it right, but there is defiantly some benefit to having something that's easy to manage over something that's not.

remember, just becouse everyone is doing it, it may not be safe. remember almost everyone thinks that firewalls are just packet filters and have no business actually looking at the packets that they let through.
