This would be the Right Way. I've got my PDP-11/73 set up for that, I still need to build the kernel driver for the Ethernet interface and get TCP/IP going. I have dozens of RX02 floppies to work through, much faster than serial, and the vtserver `rx` driver has a bug in it anyway where it continues reading past the end of the media (not harmful to the disk/drive, but you have to sit there and watch it).
