But when I go to a service that requires a proxy, I have to modify
settings in all my applications to use that proxy, then return the
settings back when I go back to a service that uses no proxy.

How can I just change one setting and have all the applications
continue just as they were (without reseting options, without
restarting them, etc...)? ÂIf they were running with providerA, and I
switch to providerB (requiring a proxy *manually* configured), they
will just keep running and working without any intervention.

I guess what I am looking for is a easy way to make the proxy happen
(and quickly changeable) downstream/upstream from the application (no
restarts), so the application knows no difference, and I change it
only in one place.

Something tells me I am going to get a really obvious simple answer?

Yep... really obvious, simple answer: There is no way to meet all of your requirements. Apps that utilize the *_proxy environment variables will need to be restarted. Many apps like firefox, chrome, etc. can be switched "live" but don't have a common method of switching them, and may not be switchable via an external program. Unfortunately, it just doesn't work in a way conducive to switching in the manner you would like.

I'd love to be proven wrong, however. Proxy settings in Linux is definitely an area that could use some love.
