How can eBay use Skype?

Since eBay acquired Skype for more than 2.5 billion dollars, how can they use Skype technology for their services? The combinations depend on the imaginations of the users of Skype and eBay. One possibility is eBay users posting links to their Skype account on their eBay listings. Skype's site has HTML code for its users to display on websites that allow people to click on links that will make Skype software call a certain user. Would a seller on eBay want to be bothered by VoIP calls about their multiple products for sale? For sellers of high priced items or barely selling any products on eBay, a Skype option would help them communicate exceptionally well with their customers.
