I guess (stressing 'guess') you could do wifi fine, if you can afford a lot of dropped packets. You would listen for some short while, and process that signal to look for packets sent your way. When you needed to send data back, you pre-process it one packet at a time, ('packets' at the wifi level, not necessarily TCP/IP) and when you hava packet you just fire it out the radio. There's a fair bit of work going on behind the scenes there, and wifi is a pretty heavy protocol to work with like this. I would be very surprised if Per Vices doesn't move to a seperate wifi chip in a future version, if they stick to the 'universal bridge' product. For such a popular protocol, it would make much much more sense.
