- This is a coincidence of names, the rvi developed here effectively
incorpates ftp within vi. It operates on a client server model in which
the client requests the server to either read in or write out a file.
All the editing takes place on the workstation. I asked the author for an
explaination of how it worked. I think the point of this work is to 
make more effective use of both the workstation and Ymp cpu cycles, not 
necessarily to avoid having screen editors on the YMP. i.e making it easier
for the user to use the machine effiecently and cheaply. Our version is
still undergoing testing, and is not generally available yet. 
I also believe a version of remacs is in development. 

( I'm not working on this project, so don't take anything I say as
a more than water cooler gossip. )

- I would second this statement. Any problems we've had with system
overhead here have not been due to screen editors.
