	Yes, possibly a wrapper script could simulate a --read-only switch to issue chmod
commands before and after Kate invocation.  A script, perhaps
named /usr/local/bin/ro-kate, containing these basic steps
| # Remember the current privileges for the file(s) passed
| # Use chmod to turn off writability for the file(s)
| # Invoke Kate upon the file(s)
| # Restore the original privileges for the file(s)
ought to work*.  Such a script could be called automagically by creating an icon for it in
one's Menu Editor.
