We're hearing rumors today that Microsoft's already hardworking Mediaroom could be putting in overtime in the near future. According to ZDNet, not only is Microsoft working on a Mediaroom client for Windows Phone (aka Rome), but it's also got a Silverlight-for-Mediaroom project (aka Taos) in the pipeline, with a possible Silverlight-for-Mediaroom STB (aka Santa Fe) also on the way. As if it didn't already have a heavy workload, the platform is also up for a possible tie-in with Windows Media Center (aka Monaco). All this comes on the heels of chatter that the software giant is considering a new Xbox 360 TV service, incorporating Mediaroom, and news of a Silverlight SOC that could be worked into an STB like Santa Fe. All code names and acronyms aside, it looks like Microsoft is gearing up to give Apple and Google some serious internet TV competition, which means Mediaroom's going to have say goodbye to happy hour and hello to some serious all-nighters.
