SONICblue paid for RMML, D&M bought the IP from the receiver, and later sold it to Sigmatel. I doubt very much whether Sigmatel are aware of this or even have a copy of the source (it was left in Mike's hands for on going maintenance which, thanks to his community spirit, was gratis after the official demise of the project). I would imagine that Sigmatel have other things on their mind right now (take a look at the share price) and I also doubt there's anyone there with the authority to assign IP who would also posess the motivation to do so. I daresay the soul remaining employee likely to have at least the latter attribute would be Peter, who frequents these forums still.

One of many loose ends I failed to tie up before jumping ship *sigh*
