command blocks are used for map making. they could be useful for long distance serial, but it is hard to make pulses for serial, and they take out the point of redstone. you could easily do /setblock redstone_block to a place to make a signal, but what is the fun in that. we don't really need a full programming language, that will require a massive computer(possibly 64 bit) and would lag out the server. i do think in the future we will see very simple RPLs, but not with command blocks.
