Reuters article on nascent scams growing up around VoIP. User trust is about the only thing I can see on the horizon likely to slow Skype's growth. Two issues. Trust in Skype itself, as a service provider, and the trust users have in VoIP service which they will inevitably compare to the 'certainties' of the PSTN. I think Skype learned lessons from Kazaa in respect to trust as a service provider. Be interesting to see how they would respond to some of the claimed VoIP vulnerabilities in the article by an unnamed AT&T source.
