While following this thread closely I like to bring another option of
proxy-usage in play.
What about the 'normal' proxy-env-vars http_proxy/https_proxy? It would
be really cool, if they would be picked up from the settings when the
checkbox 'use_proxy' is checked (like Tim suggested above).

This would simplify the use of systemwide-proxy-usage on a
multiuser-system dramaticaly, because QGIS simply picks up the correct
proxy. Though I am not sure it this works also on other OS than

Currently we are dealing with such a scenario for securing several
OGC-services(WMS/WFS) through proxy-usage. 

Best regards
