If want to control schedule and don't want technical/experiment issue 
affect schedule, using SPI. The cost will be developing SPI version of 
wi-fi driver, that will be a lot efforts again.

If Atheros could help us on the SPI driver, SPI is much preferred.

Multiplexing is very good idea, but I suggest off-line verification 
first, then put on board. And component availability also need to verify 
first.

Allen will need 1 or 2 weeks to verify component availability issue.
