Get a VPS with an unlimited bandwidth deal and set up openvpn, strongswan or even an SSH vpn (works under linux only). Get your default gateway to connect up permanently and route as much or as little traffic as you want through it. I use this for things like Hulu, so I can watch iPlayer in the UK and Hulu in the US from the same location.
You can use putty and firefox to do sock proxy on windows. When configuring a connection in Putty add a port for dynamic forwarding (under connection -> ssh -> tunnels, put something like 4999 in the source port, select the Dynamic radio button and click add next to the source port)
Then in firefox you can setup a socket proxy (in options, under advanced settings -> connection settings select
manual proxy then add 127.0.0.1 and port 4999.) This should be enough to get around it. I use this to secure my connection while on other peoples laptop (work etc..)
I use this in conjunction with the FoxyProxy[1] extension sometimes to get around censorship in some countries. Good call on writing it up here, I missed it.
