I have a number of business trips to China coming up and would like to use skype or similar to keep in touch with family at home on my MBP. It would also be good to have access to youtube (I'm a bit of a youtube addict) and facebook. China restricts access to these and other websites but I understand it may be possible to get around this using a VPN or a proxy server or similar. I have an imac at home in the UK (connected by wifi to the router) that I could use for this purpose, but have no idea how to go about setting up a VPN/server or whether it would even work. Is this an option, and if so how difficult is it to implement? Would it work for videostreaming/videochat, or would the VPN slow things down too much?
