Is that another way of saying "you're crazy!" :O)

I want / 'need' to bridge because I want to
    a) use my laptop as a wireless bridge ocassionaly
    b) link in a VDE2 tap interface onto the bridge so that test qemu
instances can get bridged onto the network properly.

I'm sure it is possible :O)

In /etc/wpa_supplicant/functions.sh in the "ifup" function used
/sbin/wpa_action.sh, it does:

                                    /sbin/ifup
"$WPA_IFACE=$WPA_LOGICAL_IFACE"

Can that be changed to an if statement that checks to see if
IF_WPA_IFACE is set, and it so uses it

      if ([ "x$IF_WPA_IFACE" == "x" ]); then /sbin/ifup
"$WPA_IFACE=$WPA_LOGICAL_IFACE"
       else; /sbin/ifup "$IF_WPA_IFACE=$WPA_LOGICAL_IFACE"
      fi

I don't know if the IF_WPA_IFACE gets passed through to that point, and
I havent tested it.

Just testing my logic :O)
