Joystiq says that the latest upgrade to Sony's PSP game machine will include DRM. Snippets:
In the most recent issue of Famitsu magazine, SCE software platform development chief Izumi Kawanishi dropped some hints about what might be in store for future PSP firmware upgrades. Kawanishi would like to add a streaming video function to the Web browser, so that users won’t have to bother downloading videos to their memory cards. In addition, there are plans to include Digital Rights Management functions that will allow for downloads/streams of paid content.
