Hmm. I prefer storing the fully-qualified multi-hop file name in the
bookmark itself. I share my bookmarks across machines which all have
identically structured file systems, identical ssh configurations,
identical "production" Emacs configs, and I expect my bookmarks to load
without having to copy over another file. I will occasionally share a
bookmark snippet with someone else and expect it to work (these people have
similar set ups--assuming they follow the configuration guidelines).

Can we take a look at fully-qualified file name reconstruction?
