    Is it possible to detect between remote and non-remote?

   For buffers associated to files, there is file-remote-p. 
   For others, stackoverflow suggests using (file-remote-p default-directory).

   I don't know how those behave if you use tramp to connect to a server which 
   then connects to the local host, or whether one using such connections would
   not want that information to be as clearly visible as a remote host.

That assumes running emacs locally, what is being discussed is if you
are running Emacs remotley, i.e. over a remote X11 connection (e.g,
ssh -X).
