I used to have a bad habit of inexplicably giving the wrong "rapid  
fire" advice even though I knew the right answer. Since fixed with a  
patch to "advice.h". Measure twice, cut once and all that...

(569A? That keyboard's going to get you in trouble one of these  
days! :-)

And if y'r wonderin' which to use for straight through, here's a good  
enough explanation:

Summary in "rule of thumb" format:
1. use 568A for new infrastructure (it's more backwardly compatible  
with phone wiring standards)
2. don't replace 568B with 568A
3. only replace 568B with 568A if you're replacing *all* of it
4. use what the heck you like for wall-to-computer cables
