I put together a list of openpgp related software at: http://www.cypherspace.org/openpgp/
this includes library only code, and add on software. Not sure about your questions about key versions, but I forwarded it to Ulf Moeller and Len Sassaman (current maintainer of mix3). >From what I've seen mix3 (pgptest app) is the closest to providing a command line. There was also Tom Zerucha's reference openPGP code, which is command line but it's alpha level code I think and no longer maintained.
