When we chose to impose those kinds of restrictions, apart from performances questions, we actually hid evil intentions! Indeed, it is a way for us to make players imagine and build ingenious processes in order to bypass those devious restrictions.
Regarding this limitation of 256 values in a logical cable, I have to admit that Jah's 16 multiplexer-demultiplexer was so well thought! It allows to put not only 256 values on a cable but 16*256, that is to say 4096 values!
And the construction is simple, elegant and modest. So a big bravo to Jah who figured out really quickly how to use the new possibilities of the EA4!
