Greg,
What Frank was alluding to was the ability of some APs and most WLAN
switch/controller-based systems to support multiple SSIDs - also called
Virtual WLANs. To get consistent and acceptable client connectivity,
the APs/WLAN controllers should support unique BSSIDs (wireless MAC
addresses) for each SSID.
At Emory, we are using Aruba equipment quite successfully to present
multiple SSIDs for guest access and WPA/WPA2. Each SSID gets mapped to
a specific VLAN and has different authentication and access rights.

I am surprised no one has brought up the issue of only being able to
broadcast one SSID. What do you do if you need/want more than one.
We currently only have one and Franks comment makes sense in that
scenario. However, assuming that we can only broadcast one, how do you
differentiate wireless if needed?
What I am hoping to achieve in the near future is 3 classes of service
(Fac/Staff, Student, and guest). (note: we use CCA for reshalls here)
Fac/staff can use their campus owned laptop and will be able to pass
right over to a VPN to get "into the network". CCA can exempt devices
we choose (e.g. campus run laptops)
Students can use their same CCA credentials to log in and use the
wireless in exactly the same manner as in the res halls. This will give
them a more consistent experience.
Guests will only be able to click "guest" in CCA and get 80 (maybe 443
and IPSec - do not know yet) out to the world.
If a student selects the Fac/Staff SSID they would fail the login so
could not go anywhere and the same is true if a Fac/Staff selects the
student SSID.

Thanks,
Greg

In an educational network where you're not try to leverage (erroneously)
the
SSID as a security tool you might as well just broadcast the SSID and
make
life easier for all the mobile clients involved -- why not?

Jim,
Yes, I have run into one particular problem when an SSID is not
broadcast. We call it a 'code 18", where the problem is 18 inches away
from the monitor. :-)
I have found that it is quite difficult for people who do not have some
experience with wireless, to set up their wireless devices when an SSID
is not being broadcast. You may be asking too much from the general
public to force their device to search for the SSID.
If the SSID is going to be used by the general then you might want to
broadcast it, in order to minimize the calls to your helpdesk.
