You might also want to think about how we could re-design the
oft-complained about buttons for go/close that change meaning when the
backup completes successfully.

It sounds similar to what we have in the grant wizard. For
consistency, I'd say both lists should look the same, but feel free to
find a nicer presentation for both dialogues if you like (not sure I
can think of one).

That's really the only way.

It was rejected by me mainly because there was no nice way of handling
it that I could picture - potentially there are nearly 15 different
versions of apps to deal with (8.0 - 8.4 of PG, EDB and GP). In
reality it's a little lower, but still... If you can come up with a
solution, I'd be happy to see it.
We'd need to have a way for us to ship one version, which might be
chosen as the default and used if the user chooses the version
override warning. We'd then need to provide a way for the user to
specify paths for other versions versions/servers that will be used
when they match the server.
