On the contrary, I think this effort with spur interest in d80211,
Atheros hardware and stimulate development of OpenHAL.  It will also put
additional pressure on Atheros to open HAL sources.

The technical ability of d80211 to handle a popular chipset would hardly
undermine its chances to be included into the kernel.  It takes more
that one step to achieve free in-kernel support for Atheros chipsets.
DadWifi may be one of those steps, OpenHAL or open-sourcing the Atheros
HAL would be the other.

If DadWifi succeeds at supplanting MadWifi, it will reduce the
proliferation of incompatible 802.11 stacks for Linux.  The FreeBSD
stack included in MadWifi will become obsolete.

There are many great ideas involving meshing networks that require
support at the 802.11 MAC layer because they are tied to the WDS
implementation.  Those efforts can be shared if the MAC layer is shared.
A company doing mesh networking on Atheros today could switch to
Broadcom tomorrow if Broadcom makes better chips, or vice versa.  
Users of DadWifi would contribute fixes that would affect users of other
chipsets.

Should d80211 be merged with the existing 802.11 stack in the kernel,
users of DadWifi would be among the testers, and they will ensure that
useful features of d80211 are not lost.

Unless I'm missing something obvious, I don't see absolutely anything
that could harm the chances of d80211 to make it to the mainline
kernel.
