I've shopped around for various grey cards, reference cards etc.  While not 
obscenely expensive, they aren't cheap either.  One idea that I've had is 
either very clever, completely stupid, or both.

I have the color profile for the printer at my local costco.  In theory I could 
create a file completely digitally with various shades of neutral grey, as well 
as a palette of reference colors, and have costco print up 4x6 prints of it for 
 $0.13 each, or $1.50 for an 8x12.  Even if they aren't perfectly dead-nuts on, 
they'll likely get me a lot closer than not using any sort of greycard or color 
reference, and at that price I can afford to print up a dozen to stick one in 
every camera bag I own.

Likewise, something similar that was business card sized would easily fit in my 
wallet.

Is there a reason, that I'm missing, that this idea is guaranteed to be a 
steaming pile of fail?

If not, is there such a file that already exists?  Maybe even one with a 
focusing/resolution target, and something approximating a distance scale?
