Also, what (if anything) would prevent implementing this on top of MPI, using existing the MPI_File_iread/iwrite routines?

How would you do this efficiently and asynchronously? you need to set atomic mode to get sequential consistency (which is not pretty and I don't think it is well supported). Even with atomic mode set, how would you guarantee serial execution order? Thanks, Mohamad
