So how do you envision remote system support in project.el?

One possibility is to have two new defgenerics,
project-local-files and project-remote-id, and to use those
internally.  But I don't see how project-files could be changed in
a backward compatible manner.  New/updated backends don't have to
implement p-files, because the result can be constructed using
p-local-files and p-remote-id.  But for old backends that only
implement project-files it's the other way around: p-local-files
and p-remote-id should rely on p-files to calculate their return
values.

What do you think?

Thanks,
Felicián
