Large boats..that travel from marina to marina. Many marinas now blanket their slips with wireless internet access, for the transient boats. Now..for single users, say a boat with a single laptop onboard...it's not bad...slap up a high gain and let them run XP's WZC. However...for several PCs on the boat...I'm trying to think of a way to have say, a router...but with the WAN port bridged to wireless. However..I guess there's no practical way to do this and have it "automatic"..as it would have to select the marinas SSID and latch on.
