This sounds like a good option.. but what do you do if you require more wires than, say, a serial cable (db25?) has?
Can you use two db25's?  And how does this effect the grounding of all the controls?

Yup, that's what I did with one of my control panels.  I just used one serial cable for the buttons and joysticks that were on one side and another serial cable for the buttons/joysticks on the other.

Seemed to work fine for me.....grounding and everything.

i have access to basically free 16 guage wire from work.  this isn't too large a guage is it?  i.e.  the extra volume of wire won't screw anything up, correct?

Mark70:
Where I'm from the quick connects are rated by colour.  Yellow, Blue, and Pink.  The pink ones are for 18-22 guage wire.  I couldn't find anything smaller than 22.  I've seen guys around here suggest 24 guage wire.  I'm going with 22 as my smallest option since I can't find a connector rated for less. 

From a design piont of view, if you have a connector that will only allow an 18 guage wire, you don't want to use a wire that will handle more than that... ie larger gauge, and you sure as hell want to be sure that you're not supplying more that than an 18 guage can handle.

Find your weakest link.  Make sure that you're not supplying more than that and then don't leat anything be weaker than that.
