 It's certainly a quick and cheap way to get a spare for an emergency.

+A technical note from Bill-at-Bose <ref>Bill-at-Bose talks about [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/5711086844?r=3931015654#3931015654 cable lengths]</ref>
+A 33 or 50 footer will not cause any problems, either with the digital audio (ones and zips) or the power.
+The technical reason follows, for those who are interested : A 24 gauge wire (the size typically used in ethernet cables) has about 2.5 Ohms of resistance per 100 feet. The T1 draws roughly 1/4 Amp on each of two supply wire pairs (+/-18V nominal).
+For a 50 foot run, each pair of wires (made up of a plus and minus lead) totals 100 feet. A quarter Amp of current across 2.5 Ohms gives, per Ohm's law, a voltage drop of less than one volt (V=IR = 0.625 Volts). Because of the margin we built into the system, it can handle this voltage drop easily.
+In fact, although we don't recommend it and can't guarantee it, the digital audio has been tested up to 100 feet in average conditions (for example, no undervoltage on the AC supply at the gig), and quite happily continued to make music.
