[comp.protocols.tcp-ip] X.400 Questions

I have two questions regarding X.400:

1) Is there currently any definition of X.400 running over TCP/IP?
Assuming that the various Internet bodies see X.400 as the way to
go (by the way, do they?), then how will they transition from SMTP
style addresses to X.400 addresses?

2) I've noticed that a lot of vendors are using X.400 as a way to
gateway between different proprietary email systems (as opposed to
incorporating X.400 style addresses directly into the user interface
of the email product).  Is my observation correct?  In the case of
using X.400 as a gateway and not incorporating X.400 style addresses
into the user interface, does it then become the duty of the X.400
administrator to setup a correspondence in the gateway between the
X.400 name and each of the corresponding names in the proprietary email
system?  This makes me think that X.400 would be expensive to maintain.
