I was revising the current our project SCM, CI and found out Google Code

http://code.google.com/

Google supports us to host any project we would like, they provides many facilities for managing project source code, and document as well, using background SVN, ReviewBoard, etc.

It should be good approach for any demo project

I would like to add more information on this matter CI, SCM, ReviewBoard, CruiseControl, VSS, DOXYGEN, FXCOP, for automating UnitTest, Code Review, Making document, measuring the code quality, bug tracking and even test automation
