Why advise WPA? WPA2 is where it's at, and to boot make Wireless access useless without it all running to a VPN gateway as well. Yet again, if you're making important financial transactions or otherwise top secret business decisions over a Wireless connection, you have to have some expectation that someone may capture it and eventually get a hold of it once they decrypt it all. Best to use a Wired connection for some of that. That way, Physical access rather than just driving within range is needed.
