Just a quick note to say you can find the free open source files for 1blankspace example apps @ github.com/ibcom.
github.com is a community based code sharing website. It allows anyone to "clone" the files required to create their own commercial or in-house app (user interface) and also contribute to the existing apps initiated by ibCom.
All apps (user interfaces) of course run on the ibCom mydigitalstructure.com platform.
You can also find more examples @ mydigitalstructure.com/examples
