Well, if you are disconnected from the internet (point #5 of your list), there is no way to display online content unless it is cached. Thunderbird 2.0 has a small memory cache, which would be purged by #4 (closing Thunderbird). A solution of this problem has been provided by bug 450456, providing a disk cache for such remote content in the upcoming 3.0 version.
