no. you can use ad-hoc mode, which is for connecting two wireless devices.
or you can run one card in AP mode, which means run it as access-point.

- - use a VPN..... separate your AP from the rest of your lan, and use VPN to 
connect to that lan.
- - WAP .... the new crypt standard for wifi
- - WEP.... !!!don't trust!!! that.... no matter what keysize, it takes minutes 
til it's cracked.

depends. you can craft your own AP, all you need is a wifi card on that 
machine.

check out monowall .... google for it.
