Never did something like this before.  I spent some time trying to
understand the code in server.el however.  Seems `server-send-string'
can be used for this.  Maybe search for the occurrences - e.g. in
`server-edit-abort' (and the rest of server.el).

The available "options" are explained in the doc of
`server-process-filter' AFAIU.  I think you are interested in those
"accepted by the client" - especially -print and -error.
