Pretty much the same for me, too. But I issue
 	cd mypath
         stty -echo
         export PAGER=/bin/cat

at the remote host prompt before 'R'.

Find-file handles remote files without (IIRC) any customization.

So
 	C-x C-f /memyself at myhost.mydomain:mypath RET
or
 	C-x C-f /ssh:memyself at myhost.mydomain:mypath RET


will pop me into a file/dired buffer after prompting for a password, if 
needed.

Nothing special in my .emacs file.

HTH,

Chuck

Yes. That IS annoying! :-(
