PGP plugin for Netscape?

I could swear I read something about a PGP plugin called livepgp, and Altavista can't find it, and I can't glimpse it in my archives of the list. Anyone got a pointer? Please post to the list; making it more likely that a search engine will find this in the future, and we won't get a rash of 'me toos.'
