So you're saying this is pretty much only useful for cheating businesses out of money by stealing internet access for your friends? How many people in your hotel room need to access the internet at one time anyway? And if you're on a business trip, shouldn't your employer cover the cost of internet access if its necessary for business. And what hotels are you staying at that charge you for internet access? Airports, truckstops, etc... might be another matter, but hotels?This could be useful for paid connections at public places such as hotels. Only one paid-internet pass would be needed, which can then be shared through the second virtualized adapter.
Ah, now there's a good, law-abiding use. Rather than wire a WAP to another part of your house (why are Linksys WAPs more expensive than their routers?), use the computer that sits inbetween, assuming its on all the time.You could even take it a step further by using the second adapter as a repeater.
