Comment 69 for bug 12893

The problem cannot be reduced to a wide system setting. Here we talk of removable media, it meens you take it and plug it wherever you want on multiple PCs. If you don't want a .Trash on your usb stick, you don't want it whatever the Ubuntu where you plug it. It means that what is needed here is a configuration file on the USB stick to prevent the .Trash creation. You can also imagine other settings like preventing the automounting of the volume. I get multiple Ubuntus and it's what I need.
