hi everyone!

we are moving houses in a month, and i'm planning to install some
decent cabling thoughout our new flat. begone, ye maze of twisty
little cables all alike :)

the idea is to run an eight-way symmetric audio multicore (shielded
pairs and an outer foil shield as well) along with 4x cat5 s/stp
cables carrying 10/100/1000baseTX ethernet in the same cable duct
over a length of about 15-20 meters.

will this lead to problems in the audio signal?

my naive hope is that since all garbage radiating from the ethernet
will be well outside the audible range it might be ok. but then
there's always the chance of something demodulating it into the
20-20k range...

does anyone here have experience with such a setup?

any hints, success and/or horror stories welcome.

jörn
