I've updated the NetVibe source with a mildly useful update: listening for
changes in SSID as well as IP Addresses. The source is hosted at http://chrisfrazier.net:8080/NetVibe on
a subversion server.
I used some
code that I found at the FurryGoat experience, modified it a little bit, and
it seems that it's at least useful in detecting if an SSID ends with
something...for example, my WiFi at work has an SSID of VelocityDatabank, so I
created a rule to look for an SSID/IP Address that EndsWith Databank. This code
definitely needs improvement, but I have found it very useful, and now I don't
have to have different network segments specified at each of the different WiFi
spots I connect to.
