Even once the F-theory dust has settled, the heterotic string remains a viable route to N=1 d=4 phenomenology and is a fertile ground for developing the mathematics of holomorphic vector bundles. Within this context, there has been recent progress in using worldsheet techniques to understand the F-terms of certain heterotic compactifications. Less is understood about their D-term cousins. In this talk I will describe some steps towards rectifying this, writing down a moduli space metric for vector bundle deformations and describing some of its properties. Such metrics are relevant physically ( to normalise Yukawa couplings) as well as in the mathematics of vector bundles (they extend the metric of Kobayashi).
