IPsec Usage Question

[Black_David@emc.com]

In Salt Lake City, I asked folks to become familiar with
existing IPsec implementations that they plan to (re)use.  I
now have a specific question about this that I need answers
to - send the answers to me directly to avoid inadvertently
revealing implementation plans (I promise to keep them
private).

Q: Does the IPsec implementation you plan to use require
	that the inner IP address be different from the outer
	IP address for traffic that is to pass through IPsec
	to the IP Storage (iSCSI, iFCP, FCIP) system?
Follow-up: If so, how do you plan to configure your system
	to securely access a peer IP Storage system from
	another vendor that also has this requirement?

The underlying concern is that requiring that the inner
and outer IP addresses always be the same would visibly
simplify the configuration required to use IPsec with
the IP Storage protocols.

Please send me the answers directly.

Thanks,
--David
