Actually it works very nicely.  emacsclient expands the local filename into an 
absolute filename (as it currenty does) and prefixes that with the Tramp prefix 
when it sends it to Emacs.  I use emacsclient no differently than if the emacs 
instance were local, and it communicates the correct filename (not only in the 
correct directory, but on the correct remote machine).

And yes this could be done with a script around emacsclient, but the script 
would have to make the filename absolute itself (because the Tramp prefix will 
make the filename look absolute already).  Obviously, not difficult, but with a 
small patch, emacsclient can do all of it out-of-the-box.
