    I have been thinking about that, seeing the high density of (non-WEP)
    wireless traffic at HAL2001 :)
    I have tried stuff like you're describing by putting my WiFi card in
    'Master' mode, setting the essid to the network's essid.
    I haven't gotten really far with this, also due to beer and other fun
    things, but afaik it should work.
    From the 'iwconfig' manpage, the section about 'mode':
    |Set the operating mode of the device, which depends
    |on the network topology. The  mode  can  be  Ad-hoc
    |(network  composed  of  only  one  cell and without
    |Access Point), Managed (network  composed  of  many
    |cells,  with roaming or with an Access Point), Mas­
    |ter (the node is the synchronisation master or  act
    |as  an  Access  Point),  Repeater (the node forward
    |packets on the air), Secondary (the node act  as  a
    |backup master/repeater) or Auto.
    So 'iwconfig eth0 essid "HAL"' and 'iwconfig eth0 mode Master' should do
    the trick (probably the other way around).
