I hadn't thought of the Tunisian looking different from the WS (which has an apperance similar to reverse stockinette). Turning the work and then working with a second strand of yarn is what makes the Cro-hook (or crochet on the double) reversible and having both sides look alike.
There is also Crochenit which uses a double ended hook. Here is a free basic stitch tutorial
from Crochenit.com and I also found a video for a bedspread technique
that shows how to use a 14" double ended hook to make fabric in any width. That would eliminate some weight from the hook (one reason for a cable) and keep the working width shorter (another reason for a 40" cable). But it doesn't address joining in the round (as in tube shape rather than decreasing to a dome shape for a hat or even flat circular shapes.)
Some time ago I remember seeing (on the Internet) point covers in red and green to place on opposite ends of your double ended hooks. Place a red cover/cap on the non-working end as a stop or stitch keeper as you pick up loops. If you set your work down, you can put a green cap on the working end, so when you return you can easily remember which way you were working. Green for go and red for stop. Then when you reach the end of a row you move the red cap and turn your work to use the un-capped end to work off your loops.
Okay, if you work the bedspread technique on a joined starting chain, you could just continue to spiral around a tube. I've not done this but would suspect it to have two different sides like Tunisian stitches.
