Would it be possible to make an add-on for wpa_supplicant for Win2k? The wpa_supplicant homepage has been down for a few weeks, so I haven't been able to mess around with it. I am putting Win2k on a HTPC and need good WPA support. Most of the other WPA clients are no longer free.

It probably is possible, but you're asking in the wrong forum. This is only for HFSLIP-related issues. Since you're looking for an addon, post in the Application Add-ons section.
