I think the answer is currently "no". I believe that there is support in
libwww for sftp, so it should be possible to dig in the code and make this an
option, but I don't know where to start. (If someone does know, and is
prepared to write up an explanation, it would be very helpful for people
intersted in working with other protocols. My current dream is that I can use
Amaya to handle mail, treating messages like it treats threaded annotations.

I have CVS access to our site through ssh, so I can edit something locally,
and then use CVS to update. You should also be able to tunnel your HTTP
puts, but you need to ask someone who knows ssh better. Finally, you coud run
an X session through an ssh tunnel, so it runs locally to your work system,
but amaya appears where you are. This is one of the great things about X, but
it is a long time since I have used the functionality and forget the
mechanics of making  it work :-(

Hope those ideas give you some leads that are useful...

cheers
