If Skype co-founder Niklas Zennstrom is looking for guidance on how to spend his eBay windfall, he might want to have lunch with eBay founder and chairman Pierre Omidyar, who has a growing investment portfolio being done through Omidyar Network. His latest investment is Digg.com, which recently raised $2.8 million, according to Silicon Beat. Omidyar's other investments include Feedster, Socialtext, Dan Gilmour's Grassroots Media and John Battelle's FM Publishing. Zennstrom may want to follow the path taken by eBay's first employee, Jeff Skoll, who has become very involved with philanthropic work. Skoll, a Montreal-native and a University of Toronto grad ( have to wave the Maple Leaf!) has also invested in a film production company. With eBay CFO Rajiv Dutta poised to become Skype's new president after his successor is found, perhaps Zennstrom better start looking for his next gig. The big question is what Zennstrom does next? After Kazaa and Skype, he'll have no problem raising venture capital - if he really needs any financial help at all - but the expectations will be sky high. There is no doubt Zennstrom will stay in the Internet space but his next move will be very intriguing and exciting. If I was a  betting man, I'd say it would be something related to streaming   video. Why video? it's a hot market, Zennstrom has already done  music and voice (which leaves video as the last the big three markets to be tackled), he knows how to build a global brand, and his track record will allow him to bring in strategic investors such as television networks and movie studios. Anyone else prepared to make a bold prediction on what the future holds for Mr. Z. (Nortel CEO Mike Zafirovski being the other one.)
