Apologies to the author but this seems like a pointless effort. Buyers of iPad/iPhone have renounced by contract their desire to run general purpose software, and have accepted an application jukebox with a vendor-approved catalogue. They do not won own general purpose computers and have not purchased such devices.

Just like no-one writes an appstore for the computer in the microwave oven, that has a fixed and very limited fixed set of "apps", it similarly makes no sense to create an alternative appstore for a locked platform.
