I can set the files to remote locations (like, e.g.,
tramp would take care of that.
myserver is not always available and I don't want my
gnus to freeze when
myserver goes down.
The behavior I want is local files which are synced to a remote location every now and then.
PS. Note that these files aren't on the same exalted level as, say,
.emacs (which is kept under
hg), so I do not want to preserve their history.
