Another option I'm looking at is Wi-Fi from each machine to the venue's 
access point/router (if available).

The main problem with using phones is the cost of the SIM plan. Over 
here, $15 AU per month (per unit) is probably the cheapest, and too 
expensive IMO.

There are data-only options via another network that is purported to be 
much cheaper.  I'm awaiting details on that service now.
