This should be possible, but I'm not finding any discussion on how:

I've got an underpowered old 2-core linux box with a DVD drive and a tiny 4GB of ram in it and a separate 16-core linux machine with 128GB of ram with no DVD drive. For a variety of reasons, moving the DVD drive would be a real pain, so I'd like to do all the raw ripping of DVDs on the machine with the drive, and all the transcoding on the machine without a DVD drive.

I see that ARM has hooks for custom scripts to run when ripping is complete, so I could write a bash script that would be invoked whenever the machine ripping raw data off discs is finished and transfer the raw data over, but how would I then tell ARM on the transcoding machine "okay, you've got more work to do"?
