According to Variety, ShowDrive will debut in the UK, where an unnamed third party will sell special devices to record Freeview over-the-air TV and store those recordings in the cloud, “where they are instantly transcoded and made available for streaming.” The devices will also allow users to use some online video apps.
That article also said that Simple.TV will announce who it will partner with in the US in January at CES. (Which was the International CES last year, but now is simply CES. But I digress.) For more details, you really ought to go read Variety.
