After a little work with pygraphviz I've returned to pydot. One of the useful methods in pygraphviz is iterdegree(). Can something analogous be done with pydot? ie: find the highest degree node so that I can set it as root?

No answer after a year and a half? I don't think there is a way with Pydot without writing some code.
But you could use NetworkX with the networkx.from_pydot() function to convert to a NetworkX graph object and then call the degree() method.
