Bill Gropp has proposed in the past developing a new partitioner along more scalable lines, such as the Teng algorithm used in Padma's 2013 SC paper (https://dl.acm.org/citation.cfm?id=2503280). Jed favors a multilevel approach which I do not understand. Its a shame that all the development time that went into PT-Scotch could not produce a scalable, open partitioner. Also, the label-push stuff seems only to work well for highly connected graphs, not meshes.
