I have a Mac, which runs Mac OS X 10.6 or Ubuntu 9.10 or Windows XP (Multiboot). Solution can be for any of the systems, whatever works better.

I have two ISPs, one can be accessed via Wi-Fi, one can be accessed via LAN. In Mac OS X I can define the priority, which network to choose first. But what I wish to do is to load-balance with both networks.

I don't want to buy extra hardware. I have some unused Wi-Fi routers if this would help.

Compiling and configuring programs in Linux is no problem for me.
