From my experience, adjusting the pitch of the audio by +4% (without altering its duration) is enough to fool Google's algorithm without being noticeable/distracting, unless you're playing the original song and the altered song side-by-side.

Seconded. DansGuardian is great. You could also use OpenDNS to filter DNS requests for sites which it flags as inappropriate. There's quite a range of configurablility as to what you can have it block access to. It solves a lot of the "accidental click" issues at our house.

Am I missing something? It wouldn't be you getting the prompt because they're using google voice, it would be you getting the prompt because YOU'RE using google voice. People who call your Google Voice number don't here anything. The purpose of you hitting one is so you can tell google voice which of your phones you want to answer the call and to avoid the answering machine problem described above.

How GrandCentral handles the cell phone dead battery voicemail problem you described is it requires you to press 1 to accept the incoming call. That way it never gets picked up by your answering machine.

Perhaps you're thinking of qemu and its accelerator module kqemu? I don't think this actually has anything to do with KDE or the "K team," as you called it, it just happens to have a k in front of its name.

You can run VirtualBox virtual machines in "headless" mode and connect to them via RDP. I suppose this is something akin to a "server" instance which isn't too difficult to do.
