Free email — why not free voicemail?

Evan Williams links to Community Voice Mail, which gives free accounts to unemployed people because they found that they have a better chance of getting jobs if employers can get in touch with them. Made me wonder: Why wouldn’t Skype do this? And that, in turn, made me wonder whether in the competitive world of online phoning someone — Yahoo, Google, eBay/Skype, MSN — will end up giving us all free voicemail.
