I run whereami in the script that runs on insert of my WLAN card so that
it reconfigures my laptop for that environment. My configuration is
slightly different in that I have mostly DHCP-assigned ethernet
addresses at various work locations and use WLAN at home. I no longer
have any static IP anywhere, although whereami includes an easily
customised sample test for this situation.
Since my WLAN access point provides a DHCP address I modified the
example DHCP test to look for the appropriate DHCP address on the
different ethernet device. This is now included in the current package
as "35wireless-lan".
If you use multiple access points, and can't know the appropriate
nameserver / routing configuration in advance, you could extend the
whereami utilities scripts to parse this information from the data
returned by DHCP - I have only one WLAN location at this stage, so I
haven't done that.

Andrew.
