It seems very hard to find an high-performance (i.e., not TI's CC3000 module), open Wifi module for a project like this. I assume that's why they choose a chip that requires a binary blob Wifi driver. Has anyone researched the open alternatives? Novena for example didn't integrate Wifi but left it to a PCIe module. Are there open PCIe modules?

edit: I should say, TI's module isn't open either. As far as I know the firmware, which includes a TCP/IP stack, isn't open.

Atheros AR7010/AR9271 has open drivers and firmware, which is the closest you'll get to "fully open" WiFi hardware today. Performance is decent, although I don't think PCIe is supported by the open firmware (only USB).
