While I don't mind dual-licensing per se, I really dislike the associated _technical_ crap that comes along with it, namely

* over-engineering and over-abstraction


I won't try to argue that these are not valid points -
except for maybe the last one because it is so subjective.
But not in this email.

I do argue that these points are not relevant to the question
of  whether or not a strict stack model of 802.11 management
and encapsulation procedures will suffice for anything more
than the most basic functionality.   That is an interesting question
that deserves an answer.

Personally, I think it will be necessary to have more shared information and procedures between driver and 802.11 stack than is convenient or elegant in a strict stack arrangement.
 But, I've been wrong before.
Perhaps a fresh start with unbiased implementation will do something wonderful. I look forward to seeing how a new implementation deals with the power-save packets in the presence of qos, crypto, and fragmentation - all of which are necessary evils
if you want to pass wifi certification tests.
