Changes
add some beacon format info.
The NZone browser interface looks very similar to the main 3DS web browser, so it's probably the same as that browser except modified.(and with video support, presumably mobiclip) The NZone beacon encryption is same as before, except some unknown fields in the cleartext was changed where 3DS will only "detect" NZone when the beacons' fields are set this way. DSi will not detect these beacons. The Best Buy NZone uses the same authentication parameter at all stores /w NZone. Accessing the server via curl does not work correctly, the server returns old content. This is likely because the NZone title sends new/different params to the server.

=== Beacon payload format ===
This seems to be identical to DS(i) NZone format except for the unknown fields, unknown if support for WPA2 was added. 3DS NZone is not region-locked like DS(i).
