for example it would only increase the price by about 3 dollars.~$1.45 for a ATtiny2313 for the I2C interface and ~$0.75 for a DIP switch to select the address.
I just found a great example of a very simple solution here, Totally user configurable... with just a few wires.http://www.ladyada.net/make/eshield/wire.htmlI think the simple solutions are often the most elegant, kudos to you, ladyada.
ok, so I wasn't totally off on the I2C thing. It sounds like a great idea, but it definitely introduces added costs(however large or small) and requires some software for the 2313.Simple jumper wires don't seem to create any additional work other than in the PCB design, and add maybe a nickel to cost for the jumper wires.... kinda seems similar to my idea about jumpers, just easier to implement.I'm gonna play with some stacky headers this weekend too.... but they are also a bit pricey... Any other ideas?

I've always gotten my stuff. Sometimes it takes a little while if you order one of their boards (waiting on a 3.3v switching regulator board atm) but the components come fast.
