Moving a lot of video packets (which WebEx does) is good for the router business!!!
The Amazing Cringely, anecdotally drops this nugget in his $7 TV Network installment.
Cisco is ponying up $3.2 Billion for Web-Ex not only because they want to compete with Microsoft in the Enterprise Software arena...but because Web-Ex can sell a heck of a lot of packet intensive video services to corporations and beyond...most recently partnering with CNBC to bring live, interactive, viewer webcam feeds into their television programing.
Who knew it was a Technological Convergence play in addition to being an Enterprise Software deal?
