CLSHACK – Simple keylogger with xinput

Here http://www.clshack.it/linux-xinput-simple-keylogger.html, they say xinput does need root privilege to read chars; so they build a keylogger exploiting this “feature”

Cool, very smart, but is this an xinput implementation bug, or is a X (Xorg/Xfree) design bug? It could be disastrous if it applies to ALL Unix…
