It looks like Microsoft may soon make good on bringing its recently acquired Skype services to the Xbox (and presumably Kinect). The company is currently seeking a software development engineer focused on Skype for the Xbox, as spotted by GI.biz. Specifically, the London listing asks for someone with "a strong technical background developing client and/or embedded software," which certainly sounds like Xbox dashboard integration.

Whether Skype functionality will replace the Xbox's current chat and video services or simply improve upon them remains to be seen.
