Peter, Thanks for the tip on that. I'll be looking out for it, although at that price, it's cheaper to buy a dedicated PC and run SpeakFreely, as you point out. Linux PDAs with good sound chips are just around the corner, apparently, and it seems that it shouldn't be too big a feat to get SpeakFreely or something similar running on them. These PDAs are a lot cheaper than the dedicated encryption hardware, such as Starium, which was going to price at around $500, last I heard. Also, because everything in the PDA is open source, it would be easier to trust it. Maybe when I have time and money to do it, and the PDAs with the necessary hardware are really shipping, I'll do some project like this. Basically, all it needs would be a full-duplex sound chip, and a built-in modem, and a reasonably fast CPU. It's just a shame that we have encryption all over the place, except for the one medium which we probably use the most: voice.
