I really liked this setup. The only point of friction for me was adding the links to the index via the crawler everytime. So I created a Firefox Extenstion to do it directly from the address-bar.

If someone is interested, you can download it from here: https://addons.mozilla.org/en-US/firefox/addon/yacy-it/

Limitation: It currently supports only YaCy running on localhost and unprotected. You might have to configure CORS as outlined here -> https://github.com/tecoholic/yacy-it#configuring-yacy
