Usually you use VPN-based approaches in this scenario. Why do you want to use
WPA? AFAIK WinXP is the first Win32 / Win64 actually supporting WPA - and
there are hardly any applications supporting non-PSK WPA shipped with wlan
cards. AFAIK wpa_supplicant/Win32 is in development and if you follow this
list, you'll find problems refering some cards.

What is a "standard AP" in you opinion?
AFAIK freeradius is an independent project not covered by hostap.

A lot of people use IPSec for these issues.

So - why don't you do this?
I guess most people just get appropriate hardware and have less problems.
