encrypted IP

Does anybody have an update on the crypto IP efforts?  I've
heard there are several commercial products, including
weakened U.S. DES versions from Semaphore Technologies,
Motorola, Hughes, and UUNET technologies.  Also, some
higher quality foreign versions.  How many of these products
interoperate across vendors?  Are there any public domain
versions available or in the works?  Any emerging standards,
so that if I wrote my own system it could interoperate with
other crypto IP based clients and servers?

thanks,

swIPe, which is a proposed network layer security protocol for the
internet, may be read about in documents available from
ftp://research.att.com/dist/mab/

A swIPe implementation should be available to the public very soon.

Various work is being conducted to produce a security infrastructure
for IPng.

These aren't actually general secure IP implementations -- they are
usually more ad hoc than that.
