Same idea here. Hotspot redirects to a page (without user/pass) and serves the first video that must be seen complete. Then, redirects to free web.
Remote stats done using collectd. Impossible on MT, because closed.
Can’t collectd be used with SNMP? Stats needed are basic here. Maybe connected users and total used data (for all users). Can’t this be done with SNMP or the Dude?
One more reason, that MT not the solution of choice for hotspots with advanced features.
Hotspot is practically absent, as said, so no problem here.
It is not a good idea, first to choose the hw, and then trying to squeeze required sw-functionality into it.
It is not for us to choose the HW 
. That’s given by our partners… So, it has to be done with MT devices, and I have to find a solution with it.
