It depends entirely on how much you want to control them, it is more limited to blocking them or unblocking them. You have the standard guest portals and user codes for access for periods of time etc.
Guests can be isolated so that they can't access anything except the internet etc.
But the traffic control is all by VLAN, as for VLANs need constant attention, since when, sounds like someone is hyping up a product that stops the need for VLANs using some rules on the controller, since all traffic is routed there. Personally I prefer none school owned devices entirely separate from our network though, on its own VLAN.
Future proofing is always an issue, it is difficult to answer that. If in 5 years time there is a sudden increase in demand on the wireless, then unify would need replacing probably, but then if it cost you 5k now, then is that a massive problem? in 5 years time, there will likely be new wireless protocols, running at faster speeds, that none of today's access points can support. Your choice may well be you spend 5-10k every 5 years on a new wireless with decent technology (unify) but not the best, or you spend 50k every 10 years on the best now. The best now, will probably be better for the next 5 years, then it would become on par for the next couple and then probably worse for the final three. It also costs you 30k more over 10 years.
Its a budget and technology balancing act.

Yes, it allows separation by vlan as mentioned above so we can use a separate vlan for guest devices. You can have them authenticate through a web portal (run by the controller software) if required.

I think there are solutions out there that can do a lot more in terms of provisioning different user groups. Admittedly we are quite a forward thinking school but the way wireless is going we want to get this right first time. Some solutions allow different QoS and rate limiting, so allowing teachers more bandwidth than students etc, doing this without the need for VLANs to my understanding. Some vendors are even now doing this at the application layer ( meraki??). I know some schools are purely after connectivity but we are looking at a more BYOD friendly solution and something that gives us real specific control of users and devices etc. If Wi-fi adoption carries on the way its going then this would be sensible no?

Or is this all overkill?
