If you can put your cards into "adhoc" mode rather than infrastructure
then no, you don't need to use a wireless router.

(Trivia: normally, a wireless base station just acts as a beacon; once stations
have associated to the base station then they talk directly between each
other where possible without transmitting specifically to the base station.
Wikipedia/Google "hidden node problem" for more information.)

I'm not sure about security on adhoc mode though! I've only ever used the
insecure one (not WPA, the easily-crackable one before that.) Someone else
may know the answer to that one.
