I know that there is a push to replace Firefox as the browser for LinuxMCE. Has anyone looked in to http://www.kylo.tv/
? I'm going to start checking it out. It is made by Hillcrest Labs http://www.hillcrestlabs.com
/ who makes a gyroscopic mouse, the Loop pointer. I have two of the loops and the Kodak theatre (still trying to find a use for the Kodak device). The Loops are pretty cool and I suspect that it will work beautifully with LinuxMCE (once I get a MD working).
Edit: They don't (yet) have a linux version. I mentioned LMCE to one of the Kylo discussion board moderators. Maybe he'll check out this project.
