Once you master the command-line, there's no point in using the
typically-more-cumbersome front ends. I ran KSSH a few times several years
ago and it was installed on SuSE 8.1 by default as far as I can tell (I have
not tried it with my more modern box yet). I had it mapped to a mouse
gensture (WayV) and a keyboard accelerator, so I sometimes invoke it by
mistake, thus I remember its existence.

Panels can interfere at times, primarily due to placement conventions. You
can customise these for a better fit and, as soon as you quit the imported
panel (e.g. <Ctrl>+C), all returns to normal. Since all panels (7 of them
here) are automatically hiding, which give more screen space, there is not
much interference when I pull GNOME panels from Ubuntu onto Linux.

A session within a session is a counter-trivial case. What happens if you
have different desktop environments combined or have identical panels
appear? Linux gives you this ability, but be aware that you are pushing the
limits and accept the consequences. *smile*

Cygwin must be losing its luster. I believe that VWWare is now free, so why
not just go for the real thing rather than emulate in some inflexible black
box?

SuSE 9.3 has it installed by default. I imagine that successors of SuSE have
not changed this policy, which includes SSH allow connections from outside
(albeit one might need to add SSH to firewall exclusions).

We have all committed crimes of geekery:
