It turns out that there is now a USB On-The-Go specification that uses a double-ended cable, and lets the devices negotiate who is master and who is slave. So: finding the cable has now become easy. But one or both PCs would have to support On-The-Go, which is both a hardware and a software question, and isn't likely. See http://www.usb.org/developers/onthego/ for more information. -- Joseph J.
