Can I use the redundant wires in CAT5 as second network cable?

I have a single CAT5 cable running from a cable modem downstairs to a router upstairs that feeds 2 PCs. I'm wondering if I could put the router downstairs and use the redundant wires in the cable going upstairs making effectively a second network cable so I could have a Snazio and Squeezebox downstairs?
 
As long as you're not wanting to use GigE, then yes, you can use the two spare pairs (blue and brown) to run an additional 10/100 feed down. Personally I'd just shove a switch at each end as hacking up network cables can make them a bit fragile.
 
Yep, you can, I did the same once for a few years. But I believe gigabit Ethernet requires either an extra pair, or an extra two pairs (I forget which), so that could be a problem if you intend to upgrade later.

edit: damn my slow typing :(

:D

GigE uses all 4 pairs btw.
 
An appropriately wired collection of sockets would give you the best of both worlds - the ability to use both pairs separately, and the ability to use all four pairs for GigE.
Someone makes them for POTS and ethernet, but I can't recall who (or if they make dual ethernet ones). Not hard to make your own though.
