One other audience member asked about running X without root privileges: that does work now, and Moblin is doing it. There are some problems remaining, though, especially with fast user switching. In the absence of a revoke() system call, there's no way to guarantee that one user isn't listening in on another. Since revoke() is known to be a hard problem, it's not clear how this issue will be resolved."[1] That seems quite interesting. ;) [1]http://lwn.net/Articles/371276/ -- Suvayu Open source is the future.
