[OLPC Networking] Some questions about mesh networking (802.11s)

I am currently working on a project that involves the deployment of an urban
802.11s mesh network (at least, the way that we currently envision it).  I
thought I would write this list as people with OLPC probably have the most
practical experience with implementing the protocol, especially on
Linux-based systems.

Is special hardware required to make 802.11s work, similar to how the
hardware needs to support "master" mode to run as an AP?  I know at least
driver support will be required, but is it possible to implement driver
support for any b/g device?

What is the average range of 802.11s?  I would assume it's comparable to
b/g, but I'm curious if that is the case.

Can an 802.11s node simultaneously act as a b/g AP over the same wireless
hardware, or does the device need two radios for that to be possible?

I've read that Linux-based 802.11s is not compatible with the FreeBSD
implementation.  Is this still the case?

If I run a DHCP server on the mesh network, can that work?

If I can place certain nodes which speak 802.11s around the mesh network
area, all with wired links to an Internet gateway, will nearby nodes always
be able to use these nodes to hop onto the Internet without traversing the
entire mesh?

Thanks to anyone with answers to any of this!
