How can I remove or disable Bonjour on OSX Lion, is it safe? I have the only one computer with OSX (wife hates OSX) so I have no other computer to bonjour with. I never needed neither network zero-configuration nor printer sharing or whatever it does. Windows it causes MDNSResponder problems.

How can I remove or disable Bonjour service?
Is it safe?
No you cannot remove Bonjour from MacOS X. There is no real good reason to do so anyway.

Also the "problem" you link to describes an issue with Bonjour installed on Windows 7, so it does not apply to you.
