Of course I wholeheartedly support the proposal for a Hampstead eruv – I don’t want to be run out of the area (Proposal to create a Jewish eruv in north London divides community, 10 June). But surely a physical eruv is an slightly outdated concept – by now shouldn’t there really be a virtual i-ruv that you can download from the appropriate app store and use anywhere? What’s more, it could be used over Wi-Fi – no need for any unsightly poles and wires.
