Here's the final version.  Attached is an EasyPose hose, with a scale length of 25 feet scaled to the size of the nozzle  It's about the correct size in Poser 7 but probably a few percent off (I didn't measure it).  There's only 14 segments, so if you bend it too much it obviously kinks (but then, so does real hose under pressure).  The handle rotates forward and back, labeled "Open-Close" when you select the handle.

When I get home I'll package it up and get it distributable and up on sharecg.
