You can switch between the empeg and Rio logos currently, using tfabris' logo editor. I'm assuming 1.1 will be the same way...

Yes. If you use the latest version of my logo editor, and your Empeg/Riocar is running version 1.02 or later of the player software, then there is an option on the file menu of the logo editor to tell it whether you own a Rio Car or an Empeg Car, and it will write the appropriate four bytes to the flash ram to tell the player which of the two logos you want it to show. I think this is explained in the readme file that comes with the logo editor.
