Does Opera Unite Bring Up New Security Concerns For Businesses?

With the announcement of Opera Unite yesterday I immediately installed and got running with the new browser. After playing with it for a bit, and going through the API I started thinking about the numerous ways it could be useful in a business environment. After going through a few ideas I had, trying to fit the pieces together with the API, I then started to wonder if corporate sysadmins around the world are scrambling to disable this type of incoming and outgoing traffic. So, the question I am posing is, what are the security concerns to a corporate network? Once some people start developing some truly useful business applications for Unite, how are these going to be balanced with any security concerns?
