I agree, it's a great idea. The limitation is that the maximum amount of data a QR code can hold is about 3kB. Assuming the encoded data is compressed - either mostly ASCII and compressed, or a custom serialization format referencing external lookup tables - you could reasonably fit around 10kB of debugging information into a single QR code. That's not too shabby.
