To restate what was in the original announcement: we're making a Connect IQ depot/app store. All the content will be free - we're not doing any direct monetization. You can see more about it in the announcement video:
What about sources? Just like a GITHub or Sourceforge. Any plans on that ?
You can always create a Github account and publish your sources there. That is what we have done. If you know Git, it is real easy - Eclipse have extremely good support for Git and Github - but if you don't know Git, you might find an easier option in SF.
