People don't have "real" names. We are not born with a unique ID burned into our souls; there is no primary key for you in the CosmosDB. Names are what people refer to each other by. My name could as easily be Big Brother as Zheng Wu, both are just as valid. To be entirely too pedantic this OP should have used the term Official Name, i.e. the name the state uses to refer to you in governmental matters.
Mod Parent up. This is true. Google still force you to agree to "Google+ Pages" Terms of Service in order to have a pseudonymic voice on YouTube.
Many people have petitioned to have the "ring all speakers" re-implemented.
There is a feature in some versions of MacOS X that allow you to create a logical Multi-Output Device for audio playback. The documentation says: "If you have several stereo output devices, you can have audio play through all of them by creating a multi-output device..." You can create a Multi-Output Device in Audio MIDI Setup.app if the feature exists in your OS. Then you could try setting the new device as the sound effects output in: System Preferences:Sound:Sound Effects:Play sound effects through:. This all presupposes that the Skype app uses the sound effects device for it's alerts and not the regular System Preferences:Sound:Output device. If skype alerts used the regular output and you have regular output set to a Multi-Output, it might be annoying if every speaker and line out is blaring your voice chats in surround sound.
Ok, so current systems can be tricked with photographs, and that seem pretty silly. But future versions could record stereo images while altering the illumination of the subject's eye. Properly functioning (attached) human eyes should have irises that dilate with extreme changes to illumination. By masking the subjects eye or eyes from the surrounding environment and changing the illumination levels over time, a complex system could measure pupil dilation characteristics to evaluate if the eye before it is valid and alive. Randomly timed flashes would be hard to predict and might cause predictable blinking in most humans in addition to dilation changes. By using stereo images, the system could also verify the 3 dimensional shape of the changing iris, which would be much harder to fake with pictures.
Add an infrared camera to mesure eye temperature and faking iris with a screen gets even harder.
Wave is the future, but does anybody know the transition plan to move the entire planet from email/IM to wave? Whats the migration path? Is wave backward compatible with email or IM?
Where are the calculations that go with a calculated risk?
