As mentioned by others, NAI currently seems bent on discouraging proliferation of existing PGP desktop packages. Part of this seeming strategy includes a refusal to sell any further licenses for commercial PGP 7.X.
Strangely, the June 2002 PC Magazine (at least where I live) includes a CDROM containing "McAfee PGP 6.5.8". The CDROM pop-up says the software is "worth $XX", so I assume this is the commercial version or some variant thereof. (I haven't tried installing it since I won't have suitable sacrificial machine for a few days.) Strange timing. Perhaps an earlier contractual arrangement had to be honored. As far as a future commercial version of PGP, at the moment this seems to be the McAffee E-Business Server and Client, which appear to be the successors to PGP Server and PGP Desktop, respectively. The desktop product now appears to depend on the presence of a Server instance in order to function. I believe the Server licenses for ~$2K US. Reference: http://www.mcafeeb2b.com/products/ebusiness.asp Puzzling that these products are not being more actively trumpeted as the worthy successors to PGP. Or have I missed a recent marketing campaign? If there are whitepapers describing a migration strategy, or the technical details of E-Business Client/Server interaction, I am not aware of them. However, I'd be happy to be proven wrong on that point, or further enlightened regarding any of the above.
