This is good.
WPA support seems to vary widely based on hardware /and/ software. That
got me thinking about VPNs again. VPN's, at least in my case, are
software-only and totally free, with good support for multiple
platforms. Then, I realized the vulnerability of using only VPN over a
wireless network.
Crackers connecting to the access point could attack the clients
directly through their unencrypted channels. I'm assuming that most
clients do not have their own firewalls. (Is that a reasonable
assumption?) The access point would have to restrict access to the VPN
port only to protect against that. Again, there's that trade-off
between convenience and security since non-VPN clients would not be able
to use the network.
