That is not true.  eBones is available legally outside the US and
includes DES encryption.

That isn't true either, unless you really meant to write, "by the way,
SOURCE CODE FOR Kerberos V5 isn't legally available..."  At least two
different vendors of Kerberos V5 technology, OpenVision and CyberSafe,
sell Kerberos V5 products outside the US.
