A couple of things:

1) You're probably better off, fewer interference problems, less signal
leakage, and the new wifi standard has much more bandwidth - enough for
HDTV...

2) IIRC, that is correct, cat 5 is not supposed to be weatherproof, and
you are supposed to "plenum cabling" in areas like attics to be
compliant with fire code... I don't remember the exact details, but if
you have any questions about building codes and standards, about any
sort of material science kind of issues, I have a relative who is a
construction specifier and can answer them definitively, just send
them to me and I'll forward them along.  This goes for anyone...

Incidentally, I was told by someone heavily involved in wifi security,
that it is possible to attach some kind of dongle to a wifi card, and
with some cards and the correct kind of software, mix the signal like
a radio so that you are decoding other frequency ranges.  He said that
it is possible to do Van Eck/TEMPEST style signal recovery using them,
and that the decoder type is quite flexible and can possible do many
other kinds of signal demodulation.  I presume that you would need to
basically write your own driver, but I can see how it could be possible.
Certainly an advanced project, but a very interesting one.
