Thinking about it a bit more, if you only encrypt, say, telnet then you've got a pretty predictable plaintext stream. If you encrypt the entire link level properly then it might be much harder to isolate the nonvariant bits of the protocols since the port and that kind of header info is not available to the attacker at that level.

What about predictabilities in the PPP datastream? # Chris Adams <adamsc@io-online.com> | http://www.io-online.com/adamsc/adamsc.htp # <cadams@acucobol.com> | send mail with subject "send PGPKEY" "That's our advantage at Microsoft; we set the standards and we can change them." --- Karen Hargrove, Microsoft (quoted in the Feb 1993 Unix Review editorial)
