I managed to get the Wi-SP running, but had some trouble. The Wi-SP didn't want to join my airport network (unprotected), even after fiddling around a dozen times. I finally took off my AIS Engine and replaced it with the dummy plug (on the Wi-SP) and it connected. My Mac Mini couldn't see the Wi-SP with IP Scanner, but my old PowerBook could. (The Mini was connected with Ethernet to my Time Capsule. Is that the reason? My old Powerbook has an add-on PCI wireless card and I'm not using the built-in airport.) From then on things went well, but I'm not near water so I can't tell if the AIS is really feeding data.

BTW, your explanations are really good but you might look at ScreenSteps for easy creation of graphic explanations. It's slick.
