I understand this.  But there might be scenarios where there
is a sister board to the AP board.

It's not just to offer WPA, but a variety of authentication
mechanisms, including a more traditional RADIUS server.

Remember, we're not just looking to support standards-based
APs and STAs, but also proprietary ones.  Ones where the
vendor could use various options.  But we'd like to stick
with standards-based ones (WPA, 11i, RADIUS) by default.

Even WPA-PSK would be nice for starters.

Yep, already noted that supplicant.  It would also be
something that could complement this solution.

Something that is servicing 802.11a/b/g STAs.

I understand this.  But I also noted various capabilities in
hostapd as well.

Yeah, I've been trying to argue such.

We don't have our own radio yet to mass produce.
We're still relying on different vendors for those.

Furthermore, we have already, and we are still further
developing our capabilities that are geared towards mesh
(eventually 802.11s) augmentation.  That means no centralized
AS, but a localized AS, possibly to each AP, with
peer-to-peer replication.

What we're looking for is a codebase so we can support a
number of additional protocols, including WPA/802.11i.

And most people aren't dealing with 802.11 that goes 10 miles
and is a mesh, with no centralized back-end.  ;->

I.e., I'm not some SOHO geek trying to build an AP.  I'm a
developer further developing our peer-to-peer authentication
framework.  Not only for our products, but in a way that
would be useful for future 802.11s developments.
