Don’t mind me, either: when it comes to software, I’m pretty much just the guy who says “wouldn’t it be cool to…” with no idea of what it would entail or how hard it would be.
I assume these are probably using 2.4ghz, but what authentication protocols does it support?
That's fair (WEP is a waste of time anyway), but you can at least support the option of using an open (unsecured) network, right?I don't believe it supports WEP, and I don't want to support WEP anyway.
Perhaps in the future there would be some sort of way to make these dongles function as one jack of a two-jack PhoneNet adapter. That is, one side would be a phone jack for wiring into the next PhoneNet Mac, and the other "jack" would be the AirTalk adapter. This way, you could bridge both networks at the same time. I am not sure how difficult it would be to pass the signals along and make it think that AirTalk is a physical phone wire (although I assume how this works, it already does somehow).
You could hook one dongle into one of the ethernetless Macs to connect it to the wireless network
