If someone sets up needed dbus-commands and scripts to do this, Queen BeeCon widget would then provide a working GUI for it.

It is just a matter of collecting all CLI commands to set/get all wanted settings to/from system. Because some of the wanted differences between profiles need something else than just setting, like running ifconfig, ifup, and such; Queen Beecon seems like a right swiss army shell to the scripts then.

edit:
Then again, this kind of approach would be suitable only for experts because GUI would be available only for switching different complex profiles. But doing it first with sh-scripts would show how much different things has to be set/get and what commands has to be run.
