Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

blogologue writes I've been playing Battlefield for some time now, and having a good ping there is important for a good gaming experience. Now I'm in the situation where I have mobile internet access from two telecom companies, and neither of those connections are stable enough to play games on, the odd ping in hundreds of milliseconds throws everything off. How can I setup a Windows client (my PC) and a Linux server (in a datacenter, connected to the internet) so that the same TCP and UDP traffic goes over both links, and the fastest packet on either link 'wins' and the other is discarded?
