I completely agree with you when it comes to things like mobile phones that AJAX and JSONp are a viable solution. But, I've found no other way to bring a 360 controller into a web page other than building my own ActiveX. XNA Framework is needed for interaction with the controller. It's funny, but if you google XNA and javascript, you'll find a lot of references to Windows 8 and metro style javascript apps which tells me there's a lot of interest somewhere in the marriage of a controller and a web page. This would eliminate my need for ActiveX altogether. I'm just not in any hurry to go buy a new version of Windows. As far as proprietary software goes, I completely agree with this too. If anyone has any interest though, I'm more than willing to share my Visual Studio solution. Tweak it to suit you and compile it yourself. It is in C# though. Just sayin'.
