If I was to cable a building tomorrow, I'd buy a lot of coloured tape, 
and colour-code each cable every foot or two. I once had to recable a 
place after rats chewed through some of the cables -- it would have been 
nice to have been able to tell at a glance which cables had to be 
replaced, rather than having to check each of them.

Among the many other jobs my father had, he was an electrician at least 
twice (first, working for the Irish PTT; second, a 'home' electrician); 
his advice to me was to stay as far away from any cables carrying AC as 
possible, because you can never tell what someone else thought was a 
good idea.

Then again, there's another America/Britain difference: 110 vs 220. (I 
remember hearing a long lecture about that when I was 6 -- MacGuyver had 
just used an exposed cable to give a heart massage.)

A former supervisor of mine once had 2 RJ11s and an RJ45 on the same 
cable, so I wouldn't think so.
