How much of a task would it be to just use connections to connect one arduino pin to the corresponding ones on the shield slots? What is preventing that?
Isn't what I showed in #18? 3 header sets, one for and arduino, 2 for slaves?
Or did you mean with wires?
You could make up a Y cable from arduino to slave using these parts from pololu.com:
Male pins to plug into the ardiuno
http://www.pololu.com/product/1931
female pins for the shields
http://www.pololu.com/product/1930
crimp housings to organize the wires
http://www.pololu.com/product/1907
can also get preterminated wires to get you  half way there

WireJunky,
I got to thinking more about your question in #10 - I think you are asking how much trouble to put essentially a jumper space at each pin to let users wire each arduino signal to a slave header? I think that would be really useful, lets users only connect what is needed & avoids signal contention between shields.
Take a while to draw up.

So something like this - each header with a jumper pad to connect the header to an arduino signal, either the one adjacent to it, or to a different one. Only +3.3, +5, and Gnd are connected.

Need to get 8 Grounds connected up still before I could order cards (in February, after the China spring  hioliday). You can almost make them out as black lines above.

All routed! Needs name cleanup, etc. before it can go out for a build cycle.

So this shield would connect, say, pin 10 on the Arduino to its corresponding pin on the shield slot?

It will connect if you put a wire between the inner hole at D10 to the middle hole.
A board with no jumpers would have no signal connected at the 3 sets of female headers, only +5, Gnd, and 3.3V.
Hmm,  no 3.3V regulator. Maybe I should add one. 5V is expected to be supplied via 5V wallwart, 4.5V battery pack, or similar.

It's possible that 3 shields and the arduino will take more current than the arduino can supply through its regulator. I suggest a separate power jack with its own 1A 5V regulator might be needed.
