   Not I, but a cheaper alternative might be the flexible installer bits sold by Home Depot -- they have a small hole in the tip to attach a fish wire and pull it back. However, this would be inferior to what you describe for the lone installer, who'd have to run back and forth.

   I've worked on about a dozen homes with low voltage guys pulling security wire. Never seen a hollow bit. Not ever. And if you think about it you never will. The strength would have to be twice as strong along the sides as a solid bit. I have seen hollow bits, but they are quite thick, and are generally used to drill out (actually around) screws.

   The flexible bits installers use are long, flexible, and have a small hole near the end of the cutting edge, about 2" from the tip. Once your're through the hole, you attach a pull wire, and pull the pull wire through the hole. Then you thread the rest of the wire(s). They are avaiable at most tool stores I have seen.

   Hope this helps

   I've seen security system and communications systems installers using long drill bits that flex and that are hollow. They allow wires to be fed through them from the drill side (near the chuck) once drilling is complete; then the drill is withdrawn and the wire is already through the hole. They look to be very handy and I can think of several times I wished I had one. Has anybody seen them or got a source for them???
