Can MultiNet be done in the Firmware?

The simple answer is yes, however we strongly advocate that the right place to implement MultiNet is as a kernel driver. Buffering imposes memory requirements that are best taken care of by the operating system, and the policy driven behavior can bloat the firmware. Additionally, by moving the intelligence into a general purpose PC, the cost of the wireless hardware can be reduced further, which is the trend for the next generation of WLAN cards we described in Section 3.2
