Connect multiple WiFi networks simultaneously
I would like to make use of multiple internet connections over wifi (specifically two Android phones with wifi tethering enabled, not hacking my neighbours' wifi!) on my Windows 7 PC. Or in other words, combine or aggregate two internet connections for better performance. I'm not a heavy user so decided to save money avoiding a wired ISP connection. Mobile internet is ok, but it would be nice to double it :)
Ideally it would result in a single virtual connection that routes the internet requests (eg from browser) through both connections. I guess it's not possible to split a TCP request over two connections, but it would still be nice if every second request alternated between connections, which would be idea for loading a page with lots of images.
