You're using full-duplex with Cat 5e? You're off spec. And now I'm
wondering if the data corruption problems you were having a few weeks
ago were a consequence of it.

Either you exaggerate or you've been doing very very wrong things
because
For me, it depends on the expected lifetime of the edge device. Right
now, for example, I don't expect any video streaming box to have a
lifetime of more than five years; by then it will be sufficiently
obsolete that it will need to be replaced. Future-proofing it isn't
important. The same applies

When I used to live in Boston, I ran cat-5e to each room of, oh, 15 different
Cambridge/Somerville apartments that I owned at one point or another. (My
standard has been two 4-pair wires to each jack plus one RG-6.) Then when I
moved to SF, I did the same thing in the house built in 1907 at the edg
