Cool project, cheap mocap is a quite an interesting field.
I would have expected a system based purely on such sensors would start to drift and accumulate errors over time. Are there any tricks used to compensate for that?

They all rely on absolute references (gravity and magnetic field) to build a non-drifting reference frame which is used to correct the integration of (angular) accelerations.
