[Zope] Editing SQL methods from Emacs (+ FTP server)?

[Stephane Bortzmeyer]

All the texts explaining the wonders of Zope tell that you can edit your DTML 
files from (X)Emacs, and not from the lame editor you get from your browser 
with the default HTML form.

It works great for DTML but ange-ftp (GNU emacs 20.7) refuses to open the SQL 
methods ("File exists but cannot be read"). Is there a solution, besides 
writing it offline and uploading it into Zope?
