Great! Consider following the upgrade instructions in the FreeBSD Handbook to
bring your system up to 6.2-PRERELEASE or 6.2-RELEASE once it's released.

You don't need hostapd to create an access point. If your card and the driver
it uses support it, you can create an access point using just ifconfig.
Unfortunately, the ndis driver does not support "hostap" mode so you can not
create a traditional "infrastructure" access point. However you should be
able to create an "ad-hoc" network by doing something like this:
ifconfig ndis0 inet 18.104.22.168 netmask 255.255.255.0 ssid your_net mediaopt adhoc
Substitute the device name, IP address, netmask, and your desired ssid above
The other wireless stations on your network will also need to be set
to "ad-hoc" mode using the same ssid.

Yep, should be no problem.

This should be possible using ndis, but I don't remember for sure offhand.

That's one option (see man 4 if_bridge), but I've found that it's easier just
to have an external subnet, a wired internal subnet and a wireless internal
subnet and let the FreeBSD box route between them. Since you've already set
the box up as a gateway, this should be completely painless (you may not even
need to do anything other than assign an IP on the new subnet to your
