Can there be multiple Access Points created on the same Ezurio radio?

Yes, actually up to three APs with different SSIDs are possible to be created on the very same 60-radio.
The 60-radio is required because it supports up to three MAC addresses.

Each AP will have to be created on the very same channel as there is only one singel radio in the 60 module.

Of course since this must all be on the same channel in the same band heavy constraints with throughput and bandwidth have to be taken in account.
