Ulanoff said it's possible that Microsoft could eventually monetize Skype through upselling, or offering a basic level of the service for free but charging for premium options. Skype's video conferencing tool, for example, comes with a price tag, so it's possible the company could offer multiplayer video conferences to Xbox Live players for an extra fee.
Skype services might turn up is on Facebook, industry watchers say. Facebook and Microsoft already have a partnership, including a Microsoft investment in the social network. It's possible that Facebook Connect (the platform that lets third parties integrate with the social network) could be used to find contacts and place Skype calls, Ulanoff said.
"I think that's certainly a possibility because right now Microsoft and Facebook, to a certain extent, might want to join forces against Google, which is looking to enrich its social services," Ulanoff said.
