You can create a Monitor Mode interface with MadWifi to read the raw
frames (http://madwifi.org/wiki/UserDocs/MonitorModeInterface), but it
is not possible to delegate the actual work of the AP into userspace or
to another application.

A part of the 802.11 AP functions has a very strict timing (sending of
Beacon frames, ACKs, RTS/CTS), which you can't emulate on a central
control machine.

It might be possible to delegate the non-critical tasks, but you'll have
to rewrite big parts of the code to remove the AP functionality from the
AP.

Kind regards,

Georg Lukas
