Virtual-FPGA-Lab VS eth10g

I wanted to know if there is any project out there that emulates an FPGA in software. The affordability of big FPGAs like the Genesys 2 board is kind of a luxury for me. So I was hoping there would be a project out there that you guys might know. The only thing close to what I found was this project: Virtual FPGA Lab, but it only supports small scale boards.

Since writing that article, I've learned how to use other simulators as well. Right now, for example, I'm working on a project that will require GTX transceivers. Without building an all Verilog (or I suppose VHDL) simulation, it'd be difficult to know (via simulation) if I have my interface to those transceivers right yet (or not). So I'm building an all Verilog simulation, to include Xilinx's simulation models of the GTX transceiver, to make sure I've got it done right. (Yes, this does include a simulated PLL to track the output of the GTX transceiver as it returns from the model of the FPGA and into my ethernet model ...)

I am working on a 10G Ethernet switch project. One of the project's goals is to go from Verilog to bitstream using only open source tools. This includes the DDR3 controller. The project is still in early development, though, so ... we'll see how far it gets.
