Re: BYOD works in some organisations, not that you'd know it from this author
Universities are a completely different kettle of fish to your normal company network. It is defined by BYOD, because the Universities are not capable of providing the number of devices needed by the students.
Basic security in a University is that you have a number of relatively untrusted networks (normally by location) that the devices attach to with fairly basic security (registered MAC address, normally), with island networks containing all of the main University servers with strong firewalls on the borders of the islands that only allow a small number of trusted services through. Within each untrusted network you will have some routing and maybe print services, but any file repository will be in the islands.
Any special access to departmental servers for specialist services is controlled on a device-by-device basis, with increasing levels of control requirements, registration and mandatory patching to allow this access.
In addition, most Universities (AFAIK) operate a blacklist policy where if a device is found to be affecting other users seriously (viruses, deliberate intrusion attempts etc.), it is prevented from connecting to any of the networks until the issue has been resolved to the satisfaction of the University techies, and normally at a fee.
So the networks that the students connect to is much more like the guest networks that companies operate (with a little more security), and the island networks are more like a core company network.
This makes the analogy much clearer, and probably puts the break between the networks in a bit more context.
