from reading "man interfaces" the best solution seems to be:
mapping wlan0
script /usr/local/sbin/find_wlan_mapping
map ESSID1 wlan0-ESSID1
map ESSID2 wlan0-ESSID2
iface wlan0-ESSID1 inet dhcp
wireless_mode Managed
wireless_essid ESSID1
iface wlan0-ESSID2 inet dhcp
wireless_mode Managed
wireless_essid ESSID2
wireless_enc s:wepkey
with /usr/local/sbin/find_wlan_mapping beeing a wrapper around
'iwlist wlan0 scanning' or the selection from the wireless-applet
q
