I'm working on implementing it, and hope to have release 0.02 out soon
after Guido releases Python 1.2. Take a look at my home page
http://www.cs.mcgill.ca/~fnord to find out more about it and see the
HTML-ized documentation; be forewarned that the available release 0.01
is quite old and out of date now.
There are people working on writing a C library that encapsulates
PGP's functionality; I don't know the status of the project. A Python
interface to that library would be another possible approach.
If your needs can be handled by just running PGP, you could construct
a command line and use the posix.system() function to execute it, or
fork off a PGP process and pipe it the information you require.
