There is a protection fuse on the VBUS line that would limit the current to about 1A. Nothing bad will happen if you bypass this fuse as long as you are careful not to short stuff while working. However, the IOIO does nothing in order to *tell* the device to charge itself at a higher rate. I'm not even sure how this is done. In other cases I've seen "fast chargers" make their presence apparent to the device by shorting the USB data lines to one another, but this is of course mutually exclusive with the ability to use USB at the same time... If you can figure out how the tablet actually switches to that mode, and if this is something that can be done in software, it might be able to help you out or at least guide you in the right direction.
