Dear Dominik, I was not fast enough to promote my own work, but I'm glad others have suggested it. I of course see now that much of it is not as good-quality as it could have been, but I still think there is a good case for associating Viśākhadatta with Yaśodharman. That said, Avantivarman the Maukhari still remains a likely candidate. And no worries about the accent in my name; I myself normally just drop it when writing an email in English.

All the best,

Daniel
