Voicemail for the Homeless?

It is being reported that Google will be offering free voicemail to the homeless of San Francisco.

Some quotes:

• "would allow someone to be able to fill out a job application, which asks for a call back number"
• "will allow clinics to share test results"
• "How do you expect your life to turn around if you can't even get information or if someone can't even get in touch with you?"
• "Having your family, friends and loved ones being able to say 'here I'm thinking about you, I love you, I want you to know you're mine, and I miss you,' can have a monumental change in one's behavior."
