Well, yes in theory, but there'd be too much practical problems...
First the transmitters would be illegal and second, any two calcs
wishing to talk to each other would have to be in range of each other's
transmitters, and third, the I2C protocol has normally only 8 bits of
address space, although there is an extension for 12 bits. Of course we
wouldn't have to use I2C, it's not designed for this kind of a large
