The ssh variation is extremely handy for a quick test, and needs zero
configuration. Just replace the Xapian directory name with one for an
appropriate stub file and snap! instant remote Recoll (although quite slow).

It's your time and your code of course, but this is a really small
weirdness for a little used feature, I feel that a word of explanation
("needs a colon before the command name, don't ask"), and a correct
exemple, would be sufficient.
