What types of features are removed? For example Atheros turbo mode can be treated like another PHY layer implementation. If it is just off-loading the implementation of standard behavior then we may actually be better off ignoring this capability and implementing the standard behavior in the host. It's not even clear to me that doing encryption is a wireless co-processor is a win. It is almost certain that the host can perform the same algorithms many times faster that an embedded wireless processor. Moving encryption onto the host reduces the latency of the connection. -- Jon Smirl jonsmirl@gmail.com
