There's no point: generics dispatch to different backends, and I don't 
think we want to have a separate project backend for "remote" files. 
It's not a real type of project.

The way to do that is to either pass the remote-ness information via 
composite return values or a global variable.

I don't think using default-directory is viable for that purpose, 
though: the "current project" is allowed to be in a totally different 
directory. So I'll mull it over a little bit more (if you're not in a 
hurry, of course), and then probably commit one of your patches. Thank you.
