Open source wireless-N gigabit router

When would a open source wireless-N gigabit router arrive? Preferably a Broadcom device so that I could run tomato firmware on it. Do include a fast CPU and larger amount of RAM so that it could be a traffic manager on my network!

Just imagine an open source system that does QoS based on protocol analysis  instead of ports! Fast CPU and large amount of RAM so that it would be a snappy device. Gigabit ports to future proof it. Woot!

I’m still dreaming.
