As Dirk said, this article doesn't say anything about any applications being created, and is mainly about existing capabilities, which don't really work with the way most businesses use/configure Cisco. They only way we could currently get it to work is to weaken security on the firewall.
The only thing I've heard from Microsoft is Cisco is free to create an app. The only word I have heard from Cisco is they cannot move forward with a Windows RT solution without Microsoft's cooperation. This is why it's troubling.
