Using DCWorkflow:

 - Start with a "classic" workflow.

 - Add a variable, "approvals_required", to the workflow.

 - Bind a script to the "after" slot for the "submit" transition; have
   this script set the value to the list of user IDs who must approve
   the content.

 - Have the "approve" transition (rename it from "publish") remove the
   current user from the list, but return to the "pending" state.

 - Add an automatic transition from "pending" state to "published", with
   a guard condition "not: approvals_required".

Tres.
