What is a "fat" or "thin" AP? A new buzzword. Googling...
Oh, it's an "intelligent" access point versus a "stupid" access point
running on a wireless switch. Got it. Most wireless AP's are "fat".
I think you'll get better answers if you disclose the manufactory and
model numbers of your existing 802.11n hardware.

Huh? I pre-configure access points all the time in advance. Many
access points have DHCP clients built in. If there's a router with a
DHCP server on site, you can pre-configure the assigned IP addresses
in the router to match the IP layout. All you need to know is the MAC
address of each access point (printed on the serial number sticker).
If it's a trade show network, where you often don't have access to the
main router, bring your own DHCP server configured for delivering IP's
to only your own access points.
If you don't have time for that, just setup the IP's on any Class C IP
block that is *NOT* used by the conference. You don't need the IP's
for anything other than configuration, and with your AP's already
pre-configured, you probably won't even need those. (Note that AP's
are wireless bridges that work on ISO Layer 2. They don't know
anything about IP addresses except for configuration).
>2 - People will be allowed to bring their own APs.
Yep. That's the way it's usually done.
You'll find that the small show networks tend to use obscure IP blocks
specifically designed to avoid clueless vendors that arrive with their
AP's and wireless routers configured with duplicated IP addresses or
totally misconfigured. The convention or trade show usually has
printed or posted guidelines for show network setup.
In addition, many larger shows use VLAN's to isolate vendors. Do
whatever you want. You won't see the neighbors stuff on the ethernet.

Again, Access Points "bridge" (MAC layer). They do not "route" (IP
layer). If you configure your AP's for some obscure RFC-1918 IP
block, then the odds are slim that you're going to get clobbered by
>there a middle-ground? Maybe mesh networks?
Perhaps it might be a good idea to ask the convention operators for a
clue as to how they have their network setup?
