Over USB, the delays are faster than a human can sense (order of a few milliseconds). Over Bluetooth, maybe 20ms one-way. This should be fairly simple, unless the electronics you're intending to connect to the IOIO have an exotic interface of some sort. One thing to consider is that the IOIO Mint that you have is not ideal for USB operation, as its battery will not last very long while charging an Android tablet. Consider putting a beefier 1S LiPo there instead.
