Skype heads for IPO of the century

Skype has made its filing with SEC, ahead of what will no doubt be the biggest IPO of the century. Interesting tidbits from the filing:

• Skype's (top-line) run rate is $812 million per year
• 28 percent of total Internet users have signed up with Skype (506 million people)
• 40 percent of calls are video-chat
• 6 percent of users pay
• Adjusted EBITDA for the first half of 2010 was $115.7 million, up 54 percent from a year ago
• The company has $85 million in cash

Add it all up and what do you get? Nothing less than the dial tone of the 21st century, I'd say.
