That's a SunRay. Sun will sell you those for $700 or so.
I don't think it can restore FULL session management (e.g. it can restore
your NEdit, but not the *file* inside your NEdit). This is because the
SunRay displays remotely-executed X Window System and Windoze (via Citrix
MetaFrame) applications. X does not have sufficient session-management
capabilities to store ALL the state. Try opening 5 gnome-terminals, telnet
to another machine inside each, then log out.
When you log back in, obviously the gnome-terminals will just be showing
the (local) shell prompt -- they will not be restored to complete
pre-logout state.
So in short: what you can do with a SunRay, you can do with Linux. In fact
the SunRay runs a stripped-down Solaris running off flash memory. You can
do this in Linux too.. but the SunRay only costs $700 and includes a
smartcard reader.
