> No captive portals. The problem isn't even so much with captive portals, but only with those actively trying to circumvent captive portal detection provided e.g. by iOS (as pointed out above). "Regular" captive portals will be captured by iOS and you can log-in via the mini browser before any requests to Facebook etc. go through - problem solved (albeit in a very hacky way). The problem only (re-)materialises when some smartass developers actively try (and succeed) to break portal detection (my guess is that they do it because iOS will close the portal once the Internet connection works, so all the nice ads they want to display just disappear).
