have you considered selling the rights to start re-manufacturing the riocar?
If the player could be sold at a profit, Sonic Blue would still be doing it.
Even when the prices were reduced to well below the manufacturing costs (10 GB players were for sale for $295) it
still took them over a month to get rid of the remaining stock.
The empeg player is very much a niche toy -- and that niche (computer geek audiophile motorhead) is pretty much filled with the 4,000 units they produced. For a little more insight (
my insight, anyway

), see
this post.
