[IDEA] proxy server with .pac

[p4trykx]

Hello
There is a nice Firefox addon called Media Hint which basically usese special rules for proxy to fool Hulu or Pandora that you are in the USA.
The trick is to use proxy just for those reqests that check the geolocation and the main traffic does not use proxy. This is much faster.
Unfortunatley XBMC does not support using .pac file

I wonder if there is a way to set up some proxy server on xbian which will handle the rules.
