- This has been discussed in alt.security.pgp. Yes, it can be easily
- implemented and indeed in the way proposed by you. Version 2.2 of PGP
- will have this feature. The only problem will be that such "multiple
- encrypted" messages will not be readable by older versions of PGP
- (just like a clearsig message is not verifiable with PGP 2.0).
