Is it possible to somehow connect two computers together and create a temporary network between them to share files? Every now and again me and a few other people need to share files, but there aren't any networks to connect to, and removable media is not really an option.
Sometimes we have used a cross-over ethernet cable to transfer files, but obviously this only scales when there are only two laptops. Someone suggested using USB with a USB hub, but that does not sound like it would work. Is there something similar, except for wi-fi?
All the laptops are Windows, with varying versions (although most being Vista) being used. Although I am really keen on getting it to work with just Windows laptops, cross platform solutions are even better.
