FYI, they've been a couple of efforts in the past to make an adapter for the IOIO which allows using arduino shields on it. Not sure if those are available for purchase anywhere but worth checking. Moreover, there's a IOIO shield made by SeeedStudio which is an adapter to their Grove system, which also has a selection of peripherals with easy connectivity.
