I've not read the whole thread. I guess:
o You want a snapshot image in an application consistency since a
power-failure consistency is not good enough.
o You want to do work on a box in which IET is running from another
box to achieve the above (that is, you want remote control for IET).
When I designed and implemented ietadm and ietd, I considered this
issue (remote control).
With the current design, ietadm and ietd comunicate by using an unix
domain socket. It was easy to implement them with a tcp socket to
enable remote control. However, because no perfect authentication
scheme is for everyone, so I chose unix domain.
If an initiator box is linux, you can execute ietadm on the IET box by
using ssh. If you prefer web interface, run apache on the IET box. If
you want RCP or SOAP interface, implemnt a daemon that can handle them
and run it on the IET box. They executes ietadm.
Generally speaking, I think that adding some new functions to ietadm
is good enough for this issue.
