   - Create AP on the same interface you are getting Internet (usually require same channel)
 - Transparent proxy (redsocks)
 - Transparent DNS proxy (hijack port 53 packets)

+- Detect NetworkManager and make sure it won't interfere (handle interface (un)managed status)
 - You can run many instances, to create many different networks. Has instances managing feature.
