I asked about this feature on the "Ask me anything" webinar and I'd like to contribute with some more details.
It would be great to have a social login feature on SMB appliances. While large companies might have their own guest network infrastructure, small businesses do not. At the same time, they have a large number of customers and partners visiting the office that might need to use the internet.
The idea is that customers using the WiFi could be identified without needing a local user. Many countries have laws which demand that all users be identified or else the connection owner may be prosecuted for the customer's actions online.
Brazil has one of these laws and being able to give our customers a feature to enforce it would be a huge advantage over the competition.
