If you're only interested in the shutting down case, then I would look
at completing Pidgin's session management code. Pidgin already
remembers a bare minimum of information, and registers itself with the
session manager. If you extended this to save open conversations and
window disposition (perhaps even current status) when a session save
is requested, you would get what you want *and* just generally make
Pidgin better and more stateful. :-)

The session management protocol has a plan for this ... when the
session manager exits, you get a SaveYourself message, and you
checkpoint then. (It can also generate a SaveYourself for other
reasons, such as user request.) Part of what you give the session
manager at that point (I don't remember the order, exactly, or how
this works in detail ... there is a rather complete account of it in
the X11 documentation) is a command line which tells how to invoke
the program such that the just-saved session can be restored.
Typically programs accomplish this just as you suggested, by dropping
a state file someplace which can be read back in.
The laws that forbid the carrying of arms are laws [that have no remedy
for evils]. They disarm only those who are neither inclined nor
determined to commit crimes.
