The ideas here are interesting, but they are going to need much better documentation to prove to me they provide $600 worth of value. For now I will stick with Boost Test which is a simple to use cross platform C++ unit testing library, and it definitely doesn't suck: http://www.boost.org/doc/libs/release/libs/test/doc/html/ind...

EDIT: I found the better documentation: http://docs.typemock.com/Isolatorpp/Default.aspx##ippHelp.ch... They have a seemingly magic way of hooking already existing classes allowing you to mock out methods without manual subclassing.
