I don't think so.  The way I look at it, file-remote-p is a normal file
operation: i.e. it first dispatches to file-name-handlers if any, and if
none it handles the case of files accessed directly via the
OS's filesystem.  Currently, this part of the implementation just always
returns nil, but it should be improved with a file-remote-regexp so
users can tell Emacs that /afs, /net, /sshfs are "OS-local filesystems
but with performance and reliability-semantics of remote files".
