Cisco buys IronPort

I was going to write a post on the story that Cisco just bought IronPort, but Richi Jennings beat me to it.  :)

I was an employee of Frontbridge Technologies when Microsoft bought us in July 2005.  A year earlier, Symantec bought Brightmail.  CipherTrust was bought by Secure Computing in 2006.  I wonder if guys like Postini and MessageLabs are next?
