I've used pgp 2.x once in a company, but noone paid any license fees. Noone even knew that would be required in some countries.

The advantage of pgp 2 is that it is fixed, no changes are made anymore and, except from attacks that require access to a computer that is supposed to be trusted, still very secure. And it exists for many platforms. For me, pgp 5 was no acceptable replacement when it came out (and considering the weak keygen on Linux I think I was proven right in my decision not to "upgrade"). For pgp 6, I could not even get the commandline version compiled on Linux, and the distributed executables are libc6 only. :-( GnuPG is becomming a good replacement for pgp 2, but has some incompatibility problems between versions. I still have some tests to do with conventional encryption file formats to start converting my encrypted archives. Pitty that GnuPG can't decrypt conventionally encrypted pgp 2 files. -- ir. J.C.A.
