How important is it to have identical speaker cable length?

This has been debunked in many papers and web sites.
I have 2 different lengths of cable and if you can hear a difference I have a fuse to sell you.

It is very important to have the same speaker cable length because the sound will change with different cable lengths but, you will only hear that on certain types of speakers.

The ONLY difference in wire lengths would be a very small amount of inductance capacitance.  Certainly nothing that would be audible.

At least arch2 is keeping it real. I would also be more inclined to have same length of cables for L/R speakers purely due to OCD. I would speculate though that coiling one cable vs other being straight has more chance of resulting in actual audible difference. 

Doesn’t matter but unless you are making your own cables, aren’t they usually packaged in matching pairs?
