1. Is there a way to implement Gaze functionality into an ASP.NET app ?
This should be perfectly possible as the stream engine is built for the .NET architecture.. please do try it out and let us know how you get on.
2. Is there a legal problem with me uploading the Tobii DLLs as part of my public project to GitHub ?
You may include the Tobii DLL’s in your project freely assuming of course you adhere to the licence restrictions regarding analytical or research usage.
