Robotics Automation Studio 8: reading in parallel from a share drive

Our customer plans on running instances of the Robotics runtime on multiple client machines, with each machine polling a share drive to see if new work has come in. The files arrive in CSV format, which the automation will copy to it's own local drive, open and read the file, and input the contents into a locally installed application. The trick comes in co-ordinating the share drive access.

We configured the automation to monitor the share drive and want the first one to detect OnCreate to move the file to its own local. However, multiple clients detect OnCreate simultaneously, with all but one failing the Move because the file is no longer there (or in use). What is the standard best practice for handling this situation?

Of course we can create a round-robin shell script to dole the CSV files out to the clients, but because the files take different times to process we would rather a mechanism whereby machines which are idle go to the share and pick up work.
