Only retrieve the selection when the user explicitly asks, and then save
it to a file, which will be available to set as the selection later,
even if the program exits. (And keep track of any necessary infomation
about the selection so that it's mime type and perhaps the file (if any)
that the selection originated in would be available. Then you could have
an "open original" option in the clipboard interface to let you launch a
program with the original document, in case your selection is not quite
in the right place, for example. (that would be really cool. Something
to think about for whoever is writing the IDL.))

I was considering writing a panel applet as an interface to a text
clipboard that would work like xclipboard, with one button to retrieve
the selection, one button to set the selection to the most recently
retrieved selection, and history available via the context menu.

This might not be a bad starting point. But ultimately a generic
clipboard that works with any mime type would be very nice to have. I
know gtk's selection mechanisms fairly well from working on my character
picker applet, but I know next to nothing about IDL and corba, so I
wasn't sure I should work on something that would be done the wrong way
and would be completely superceded once the real gnome clipboard is in
place. Still, a panel applet clipboard interface would be quite useful,
and it can always be gutted later.

This would be cool. But I think it should be in addition to a history,
not instead of one. I don't like cluttering up my desktop.
