The only thing I can find for this in Kate is Menu => Tools => Read-Only Mode. There is no command-line switch for this, nor can I find a DCOP function that toggles the setting; so one would have to first open the document, then use the Tools menu to disable writing, which seems quite error-prone. :-( It is, of course, possible that I've overlooked something.
