Help For Beginner - Communicate between SX'es?

My project has ALOT of inputs and outputs. Aprrox 22 Inputs and 24 Oututs needed. So this is much more than even the 44pin SX can handle. So I was thinking of having one of the SX just handle inputs and another handle outputs and just serial between them (so only use 1 or 2 lines for comm). I was almost thinking of sending a serial strip of info every so often defining input status. Like (11011001) as in Input1=hi; Input2=hi; Input3=lo; etc.

Anyone able to lead me in the right direction on how to accomplish this? I've done minor playing around with the SX proto board, but not a whole lot. I have a fair amount of experience in electronics, just kinda new to the MC world. Links to guides, or a laymans directions would be much appreciated. Thanks in advance!

Oh, about 6 of the inputs and 6 of the outputs are analog, but I was going to wait to tackle that one.
