So there's a sleep tracking EEG gadget and a meditation EEG gadget, but not one that can do both.<p>I would like it if these devices all communicated over a common protocol so the sensor bands could be separated from the software.<p>I dissected the OCZ Nia protocol once and it wasn't pretty, it seemed a lot of smoothing happened in the proprietary driver. Maybe these devices all have the same issue, making smoothing in each band's firmware cost prohibitive.
