There certainly would be many Linux users interested in better Blu-ray support!
Not interested, I'm not using blu-rays. And bringing support for DRM in Gstreamer sounds like a very controversial topic. Many won't like that garbage to be present anywhere in the system.
And? Who cares what they think? There are plenty of us that would like to get Bluray support so we could rip the free Bluray discs at the library and the $1.25 24 hour rentals from Redbox for our HTPC.
