Ask HN: Anyone have any contact info at MSFT for developer.xboxlive.com access?

I'm a hobbyist Xbox dev and ex-MSFT employee, so I've had a few people within the Xbox group to which I can ask this question, but so far I'm coming up blank on any ideas from those folks. I have a friend at a regional cable provider that wants to create an XBox app for their company, along the lines of the Netflix/Hulu/Verizon/Xfinity streaming apps that are out now for the console. The Silverlight stuff for XBox is a completely different project with different requirements than plebian XNA devs like me, and I'm having a hard time finding out who they can contact to work out the NDA and the relevant agreements. I'm coming up completely snake-eyes on finding even an email address at MSFT for them to contact. As kind of a last resort, anyone here know anyone there that I could hook them up with that might even know anything about the process? Thanks! (first "Ask HN" submission from me, if this is inappropriate, I'll gladly remove and ask elsewhere.)
