See comment in-line You say you do not want to go back to Aironet? Aruba's security architecture requires all traffic to go back to a mobility controller, so for that reason Aruba has lower-end model (the 200) that you can place at the remote location so that traffic does not have to traverse the WAN.
FYI.... Aruba can terminate traffic locally (per SSID) when using the Remote AP. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
