I know, I should try first. Just asking since I don't have the hardware ready.
How do you send your running MoodleBox as a single file to another person? Is it as simple as making a dd file of the SD card, give it to the other person to be dd'd back to his SD card?

Yes.
But instead of using (I just re-read you need a single file)dd, I'll suggest to use rpi-clone, as explained here.
Instead of dd, one interesting solution is to use RonR Image File Utilities, specifically his image-backup tool. Then image-shrink will shrink the image to the minimum possible.
Note: I use image-shrink in the process of producing the official MoodleBox image.
Indeed, a running MoodleBox is perfectly shared as easy as issuing a disk image write of the SD card using the dd command. This makes a bit-for-bit image of the entire SD card, including the operating system, document this option should work for a wiki page. You can also compress the .img file to reduce file size when you share it to another person that will write it on their SD card using dd and maybe Balena Etcher. You would just need to make sure both SD cards are the same or that the target is a bit larger when processing for flashing.
