[Seaside] Seaside/Squeak/Linux: service with GUI as needed

With respect to "plug it in and throw the switch," you mention that it
is possible. Are there any tricks to it, other than setting up the
Squeak/Pharo image as a service? Are the following links worthy of
Re configuration, most of it would be things that I would do through
Seaside. The exact details (Seaside served from "the" image doing the
work, or a Seaside image along side of other images doing the real work)
will depend on my experience with reliability. I have read widely
differing reports on what to expect, and need to try it. My BibTeX
gizmo looks like it will be the sentinel.
OmniBrowser is prominent in your reply. What feature(s) of it earn that
RemoteFrameBuffer looks like it could be very useful, though it appears
to encrypt only for password exchange. Do you have any concerns about
its security? Assuming I am seriously paranoid about such things (gotta
be with medical records), should *I* be concerned about its security? I
reserve the right to be concerned regardless of your reply, but I am
curious about your take on it.

That's already possible.

What configuration tasks? If these are not yet available an interface
could certainly be built. OmniBrowser and the XUL integration is also
a possibility here.

RemoteFrameBuffer is perfect to do that. Like this you start you image
headless on the server, and use a VNC client to connect to the screen
from anywhere. I use that on all my servers.

Linux is great for deployment. A long time ago I did some deployment
on Windows servers. What's inside the image (e.g. RemoteFrameBuffer)
works equally well. The host OS is not so cool ...
