I can’t speak for the authors, but I have been lucky enough to be collaborating with them on behalf of the Apache Cassandra project, to refine and prove the correctness of the Accord protocol - a derivative of EPaxos we have integrated into the database.

It would be fantastic if such a project could be pursued for this variant, which has the distinction of being the only “real world” implementation.

Either way, thank you for the original EPaxos paper - it has been a privilege to convert its intuitions into a practical system.
