There is so much good stuff about this PoC that I don't have time to write it all down, but just imagine doing security review and Threat-Modelling using it.
One thing I noticed is that there isn't an VisualStudio Plug-in, so I maybe I could use the newly released VisualStudio C# REPL - O2 Platform extension to create one :)
Note how the website is nice and clean. It was made with Twitter BootStrap and I really want O2Platform.com (and the mini tools created by O2) to look like that!!!
