Right, the USB-storage access would have to lock the file system from 
the rest of the system.

FAT or whatever file system is used on the medium, right?

The downside of MTP seems to be poor compatibility with free operating 
systems. It is a bit ironic that I have not managed to get a MTP 
connection from my GNU/Linux computer to my Android/Linux phone.

Right, but which USB profile would that fit? Or how would it work 
without writing a USB device driver? Wouldn't it also nicely turn around 
the roles of USB host and USB device? :-)
