Black Hole
May contain traces of nut
The problem is now solved.
I have recently updated to a smart-phone with data (Samsung Galaxy A3) and ditched my MiFi, and connecting to its WiFi hot-spot provides each client with Internet access... but also (unlike the MiFi) allows the clients to see each other on the network.
Thus I am now able to fit the relevant HDR-FOX with a WiFi dongle, set it up to access the hot-spot, and access the WebIF with the iPad (tested, proven).
