yes, it's called device pairing (XChangePointerKeyboardPairing), but
grabs are hardly affected by it. the main reason for pairing is to
obtain necessary data (e.g. some events have both keyboard and mouse
data, here we use the paired device to get the data). Also handy for
focus setting, and - in some cases - for core grabs.

XKB is AFAIK not XInput aware, so I haven't managed to get different
layouts working yet.

as daniels said, without i-h there wouldn't be MPX.

uhm, no. MPX is pretty unique right now. You can use client-side
solutions, but they all suck for one reason or another.
