Here is an exchange I had with the folks at MIT who did PGP2.6. I've suggested that they delay their anti-patent-infringement gadgetry until PGP2.6 is more widely available for _all_ platforms.

...

I use a Macintosh. Is there a Mac PGP 2.6?

Me too. Hopefully we will have a MacPGP 2.6 shortly (I am not sure whether we will do the port at MIT, or whether the traditional MacPGP development team will do it, probably the later).

Perhaps you should delay the expiration of old, pre-RSAREF PGP keys until after a Mac version is available. That would avoid cutting off a large part of the populace.
