Do you permit X11 via proxy firewall?

[ArkanoiD <ark () eltex net>]

And, if yes, how do you implement it?
Using legacy X11 proxies that perform uninspected (though authorized)
circuit relays, similar to TIS/NAI x-gw? Using something similar to 
xorg's xfwp (which does not seem to be compatible with older X servers)?

Or is x11 firewall support just a useless tradition?
