Don't know about the parachuting in bit and most people won't have/use computers, but mobiles are making big impact/inroads in third/developing worlds. Ideally do something using them. So, perhaps a text based mobile service (most places do not have mobile-internet yet) to do something useful may be of value e.g. to find the current market price of rice (to buy/sell without being cheated) or warn about events like potential flood/hurricane risk or when the next bus is coming or text-based bartering system or even just teaching the kids how to use the OLPCs effectively.
