Labeling is good. As I've tried to follow the pace of this thread, I 
appreciate where someone else stated that (paraphrased) "males 
essentially have a problem with identifying colours". I personally am 
relatively colour blind (mostly red-orange are the same, as is black-green).

A very good friend of mine who is relatively quite older than I, used to 
run what we (I) would call now the 'IT' department in the Butterfield 
Bank of Bermuda way back years ago (relative), showed me pictures of 
closets which had numerous hundreds of Token Ring MAU connectors, 
attached to cabling dozens of feet long stretched down a corridor 100' 
at least after an effort to 'untangle' the typical 'this needs to be 
patched *to this floor*'.

I will forever remember those pictures, and forever know that no matter 
how badly labeled/coloured an Ethernet infrastructure environment is, it 
can never be as bad as having several hundreds of cables as thick as my 
baby finger, all the same colour, entangled in a mess worse than 
anything I've seen.

I would like to know ANYONE who has a policy strict enough, and enforces 
it so as to have even an almost perfect cabling 
there such a thing?

God bless CATx cable, especially when it terminates within the same area 
that it originates from ;)
