principal bundles with connection and differential K-theory

Idea

We apply the general formalism of differential cohomology - nonabelian case to the case of nonabelian cohomology with coeffients in the delooping $BG$ of an ordinary nonabelian Lie group $G$.

In particular, we consider the case that $G=U$ is the unitary group and show that in this case our general abstract nonsense definition reproduces the notions of Simons-Sullivan structured bundles with connection that may be used to model differential K-theory.
