at some point I was able to do this via tex->dvi->postscript->pdf conversion - basically getting the font installed in ghostscript let me use it directly from graphviz when rendering to eps and installing the font into the tex/postscript machinery let me also reference the same font. granted, this was not fun, and also now 'modern' tex (not sure about graphviz) will use fontconfig on linux which may require different machinations. so obviously your point on 'better integration' still stands unless I'm just out of date on how to do it..
