Luis,
please correct me if I'm wrong. It seems to me that softmac drivers will need 
significant changes relative to the model that HostAP employ. Also, many 
changes dictated by QoS (TGe), if one want to really implement it. Will your 
product support TGe?
May be, we need to do design for generic "softmac" that will be then used with 
different PHY's. Question is, whether we can formally describe boundary 
between softmac and PHY.
I am interesting in joining this "softmac" development, as I will do some 
other .11 card which is "softmac". Can't reveal details yet, but we may 
discuss softmac issues without disclosing private info (I don't want to lose 
my job).

Vladimir.
