For those of you who thought the killer app for the PS3 was being able to play with others online, a Japanese company is now catering for more solitary pleasures with the launch of a streaming service offering on-demand HD adult movies.

DMM.tv works by loading software into an internet-connected Sony console using a Blu-ray Disc the company will send out free of charge, and then it's just a matter of setting up an account and browsing or searching for the title or genre you require.

Any time you feel the need, you just load up the disc, and follow the menus to stream whatever you want, or download it for your later viewing pleasure.

Kind of reminds me of a conversation I once had with the head of the home entertainment division of one of the Japanese majors around the time of the launch of DVD. He told me, after cold drinks had been taken, that much of the success of the then new format would depend on how quickly the adult movie industry adopted it.

"After all, Everard-san, DVD is perfect for adult movies – so much better than VHS," he said.

"Why?" I asked, aware that the players about to go on sale were £500 or more, while cheap and almost ubiquitous VHS machines would seem to offer a more attractive market for the pornsters.

"Simple," the consumer electronics bosu replied. "A-B repeat".
