Heh... I would say that I'm an MS hater, but I'm certinaly not a fan, prefering open solutions (open source and standards) wherever possible... Why is why I don't use proprietary Skype, prefering the open SIP standard!

The "trouble" will come when it's a standard part on every desktop, home and office. Then it will be interesting to see what happens..
