[SI-LIST] Common mode clock coupling

Suppose I have two clock lines that run parallel to each other for a 
significant distance (6" or 12"). They are completely synchronous (equal 
signal). Assume also that they are series (source) terminated.

These two lines are (perfectly) common mode coupled (as opposed to 
differential). I have two questions:

1. What are the cross-talk implications, if any?
2. Are the cross talk implications different if they   are/are 
not   matched length?


Thanks for any input
