From News.com "Yahoo is gauging demand for new instant messaging features that would allow people to listen to music while chatting, or manage a single address book from IM."

So we may be beginning to see the integration of messaging, voice and media-rich applications. As noted in Voice is a Feature, over time, I would imagine that the provision of dialtone and basic advanced features becomes a commodity with the value continuing to migrate to the providers of higher levels of value-add. Marketing and product differentiation will remain the key.

Entrepreneurs looking at the VoIP market could do well to listen to the wisdom of a seasoned marketing pro, John Scully. "The innovation now is taking place with things that are largely being driven by market opportunities and customers."
