[Chilli] Multiple SSID, multiple uamhome, and multiple radius server ?

[Ming-Ching Tiew]

There is this idea that one want to host multiple captive portals using the same access controller. So the idea is that by exposing multiple SSID, when a user connects to a separate Wireless SSID, he is prompted with different uam home login page, and then authenticated against different radius server.

Is this possible at all ? 

Running multiple coova chilli on the same hardware each listening to separate VLAN dhcp interface ?

Another idea is to just run one copy of coova chilli, but enable VLAN support. The user coming in from each SSID corresponds to a separate VLAN ID. When the VLAN information is passed to the http server, it detects the VLAN ID and present the user with different login page. Is this a possible solution ?

But still coova chilli will pass all authentication to the same radius server. Perhaps even the radius server need to pick up the VLAN ID and treat them as separate realm and authenticate them differently ?

Has anyone encountered this situation before and what is the most elegant way out to this ?
