From the first time I ever used Skype, I wanted to use it from the living room on a large screen TV. Unfortunately, there weren't a lot of otb solutions for that at the time.
So I thought it'd probably be easy to just build an inexpensive prototype of a Skype set-top box using OEM parts, install Linux and write some software that uses the Skype API. Maybe there's even a niche market for one of those, so I put up a simple site to do some market research:
Skype sent me a C&D for the domain SkypeForTV.com (interesting how that domain redirects to bing.com now that MS bought Skype), so I moved the poll to here, however it looks like Skype had an even bigger reason for me to take down my poll, they were working on their own version of the set-top box.
