I would go with what gfretwell said as the first response. The 'neat and workmanlike' part could be achieved by stripping off ~12 inches of the sheathing, terminate into the plug at one end with the ground doubled back out of the plug, and use some sleeving and a crimp lug to attach the drain to a convenient ground. I have seen this done at patchpanels here in the UK on occasion, when cat5 has been used in an 'electrically noisy' environment, didn't seem to cause any problems at 10BaseT speeds.
