[c-nsp] wireless lan controller and remote ap

[Dan]

Hello,

I'm interested in deploying a wireless lan in a school district.  There 
are 19 buildings connected via wireless bridges.  I need about 45 access 
pointed in total and I was looking at the 4400 series of wireless lan 
controllers.  I was wondering if it is possible to have one controller 
centrally located and have remote access points in the buildings managed 
by the controller.  The only catch is I don't want all of the traffic 
going back to the wireless lan controller, I would like the network 
traffic to go back to the main switch, because the users will be logging 
in locally, and just the management traffic to go back to the controller.

I have been getting different answers from many people including cisco 
pre-sales, so I was wondering if anyone had real work experience with 
this type of application?

Please let me know if I was not clear.
Thanks,
Dan.
