Regarding 1., I actually had an idea for a complete communication suite (email, voice, texting) but anonimized. The realization came when I was exchanging contact info with a stranger on CL who was selling an iPhone.Why was this person now privy to my G+ profile? my phone number? etc... The service would create "channels", each with a temporary telephone number (that works with texting) and an email. You use these to communicate with the seller/buyer/whatever and when you're done you disable the channel. To communicate you would download an app to your phone that allows you to view messages and reply, or even place calls. Anyways I didn't build it because I wasn't passionate enough about the idea, and I figured it would mostly be used for nefarious purposes. Also, there are some legal implications if somebody becomes the victim of a crime while meeting someone using my anonimized communication service. Implementation of this technical problem left as an exercise for the person who "steals" this idea.
