What a WASTE...

So, after doing all of this research on cryptography, and law, and circumvention being a generally bad thing (thus sayeth Congress, at the behest of Copyright Owners everywhere), I started looking for privacy products on the web. I found two that are kind of interesting.
The first one is PGP - Pretty Good Privacy, which allows me to encrypt all of my email. It's supposed to be easy to use, easy to encode, and easy to decode. But I don't know anyone else that uses it, and I don't really have anything all that subversive to say. Maybe when I get into actual legal practice, it'll be more important to encrypt my e-mails. (Thank you The Practice for showing the way).
The other one is WASTE, a program that allows encrypted chat, messaging, and (disturbingly enough) file sharing. This one has an interesting history. Apparently, it was created initially by the folks at Nullsoft, creators of (among other things), Winamp. It was up for a short period of time, and then it was taken back down. But enough copies of it got out that people have been working on it. And that's more interesting to me, just because I think IM is kind of where we're heading, and that's probably interceptable the same way e-mail is.
So, I've got two privacy protectors here, but no-one to play with.
Also, there are some real questions in my mind as to who can and can't use Waste - Nullsoft claims that they've revoked any and all licenses to the original program. But the copy I found was created within the last month, and is being distributed under a GPL. So, whose program is it?
Something to think about while I'm (not) studying, I guess.
