Unfortunately Synaptics isn't the most straight-forward example, but:
http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/tree/src/synaptics.c#n1397
http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/tree/src/synaptics.c#n2881

That handles the button emulation for you in the server, so you just
post one axis event and it works across all clients.

Cheers,
Daniel
