After a little thinking, I came up with the following solution that makes use of iPhone apps with WiFi syncing and the Airport menu's create network command.
First I tried setting up a network with the Mac, but an iPhone won't stay on a WiFi network unless it has an internet connection. So while I could initially find the network from my iPhone, it wouldn't stay connected.
It turns out you can defeat this by turning off 3G and Cellular Data in the Network section of General Settings.
With 3G and Cellular Data switched off, you can open up WiFi settings on your iPhone and select the network you've created with your Mac. In a minute, you should see the WiFi bars on your iPhone and you can sync using an app like Things that uses a shared WiFi network between devices.
