As you've noticed, VDR only accepts properly ordered devices, and stops after first device that is not present. This could surely be fixed easily, and I think there have been existing patches for this. While on that, allowing to use DVB names other than /dev/dvb/ adapterX would be nice. Adding devices dynamically should also be solveable with some care, the device list just needs to be extended. An easy way would be to poll frequently for new devices, or on manual request. Removing devices however is really difficult. There's currently no mechanism to unload a device before VDR is exiting. Also, removing devices throws some questions, like what to do with running recorings (re-tune to other devices, possibly cancelling lower priority recordings?), and how to properly shut down all background access. Finally, device removal needs to be detected, as the removed device will continue to exist until being closed. All in all, solveable, but probably not very high on the todo list...
