Hello Marco,

It might be possible to modify and add such a key feature to my `mtx-changer-python.py` drop-in replacement script:

https://github.com/waa/mtx-changer-python

...which includes the ability to:

- intercept the unload process
- check if the drive wants to be cleaned
- actual
ly load a cleaning tape
- wait
- then unload it
- and then return control to the SD

Maybe during the load function we can add a call to a new function (yet to be written) which could verify that the keys are 
loaded?

Let me know what you think.

Sounds like an interesting project. :)


Best regards,
Bill
