It's been 2 weeks where are the apps?

It's been 2 weeks since google released the chromecast sdk was released to the general public, and the only app that i have seen that has used it, is allcast. He said it only took 20 min of work to get the app chromecast enabled, so why has there been no other app that has used it. I heard that the guys over at shiftyJelly had it working in Pocket Cast when the sdk was in preview. What is taking so long? I know that 2 weeks is not a huge amount of time however I thought that the sdk was meant to be easy to implement.
