Short answer:
You can pre-arrange for this to work with command-line tools. Except in
a very limited sense, you can't do this with graphical tools.
Long answer:
There are various ways to set up an rc session (or any command-line
tool) so that you can reattach later, but you need to arrange for that ahead of
time. The simplest, using all tools which come with the system, is probably
running:
srv -e 'rc' whatever
and then using "con /srv/whatever" to connect to it later. I use this for a few
system services, as it has the fewest moving parts, but it's imperfect
(especially for a shell), because local echo won't always be what you expect,
you can't get at the file descriptors in all the ways you might like, multiple
readers/writers will get screwed up, &c.
A good solution which is much more flexible and general, but somewhat
more involved to set up and learn, is hubfs, available from contrib. See here:
http://plan9.bell-labs.com/wiki/plan9/Hubfs/index.html
As far as I'm aware, there isn't an existing way to do this with
graphical programs. Hubfs will allow you to do it in some very limited ways,
but it's almost certainly not what you're after.
In cases where this manner of persistence really matters, we have VNC,
although that's obviously unsatisfactory on other fronts. The group at LSUB was
doing some great work with a "plan 9 way" of accomplishing this goal in Octopus
(http://lsub.org/ls/octopus.html); I don't believe they're still working on
that, though.
